Statement and Argument - Reasoning Video lecture in Hindi. It covers the IBPS and SBI Bank PO / Clerk Examinations. This is a Completely free study material especially designed for students preparing for IBPS SBI Bank PO / Clerk Examinations. Title : Statement and Argument for IBPS Bank PO/ Clerk (Hindi Video) Study Material Chapter Name : Statement and Argument Subject : Reasoning ( Verbal Reasoning ) Exams : SBI PO, IBPS PO, SBI Clerk, IBPS Clerk, IBPS RRB, RBI, LIC AAO etc. Language: Hindi (Terms in English) Format : Video Lectures Topic Covered : 1. Statement and Argument Keywords : statement and argument for bank po, statement and argument reasoning, statement and argument questions and answers, statement argument type questions Brief Introduction : In this type of questions, a statement (usually an interrogative sentence) in the form of a suggested course of action is followed by two arguments. One argument generally supports the given statement (or suggested course of action) by pointing out some positive features or positive results of that action while the second argument denies the statement or argues against it by pointing out the negative features or deleterious effect/result of that action. In order to determine the forcefulness of the arguments we have to decide whether the argument is perfect or not. If an argument is hundred per cent perfect, it would be forceful. Remember that : (i) The argument should not be just an opinion. It must answer one of the questions Why, How. When, What - of the statement. Otherwise it is not an argument. (ii) An argument also depends on the language used because by changing a few words we can make a weak argument forceful. (iii) The argument must be judged as an argument and not with what somebody or newspapers say (s). Ex. Statement : Should we follow non alignment as foreign policy ? Argument : Yes, because Pt. Jawaharlal Nehru advocated it. Explanation : The argument is not forceful. If somebody says in favour of any policy or adopts it, that does not mean that it is a correct policy. (iv) If some one is quoted in support of the statement it cannot be a forceful argument. Ex. Statement : Is child the father of man ? Argument : Yes, because Wordsworth has said, 'Heaven lies about us in our infancy.' Explanation : The argument cannot be forceful only because someone has quoted in support of the statement. Some Important Tips (A) If an argument is an assumption, that is, fit assumes something to be true whereas in reality it may or may not be true, the argument cannot be forceful (B) An ambiguous argument cannot be forceful. The argument must be clear in meaning otherwise it may not be forceful or strong. An ambiguous argument leaves a doubtful and confused impression. (C) If the argument is inform of a simple sentence lacking any facts or established notions but is not ambiguous cannot be forceful. Such argument shows proper relation with the statement but due to its simplicity, it cannot he considered a forceful or strong argument. (D) If the argument is superfluous and only glances at the theme without making an indepth analysis of the facts or information, the argument cannot be forceful. (E) The 'Law of Identity' must not be violated. In other words, a word or phrase should be used in the same sense in the statement as well as in the argument. In the foregoing discussion, we have provided sufficient clues for rejecting an argument at a glance. However, it does not work in every type of arguments. In some cases, a argument appears to be forceful at a first glance but when we analyse it properly, it does not hold strong. Therefore, it is necessary to provide some basic tips so that you can identify such arguments. WEAK ARGUMENTS Weak arguments are those which are of minor importance and also may not be directly related to the statement or may be related to a trivial aspect of the question/statement. You can declare an argument as weak on the basis of the following grounds : I. If it is an established fact that such a result as mentioned in the argument would not follow an action suggested in the statement. II. If experiences predict that the result will not follow. III. If logically the result is not probable. That means, if we analyse the result it does not appear to be logically sound. IV An argument should not be factually incorrect. The argument must not violate the prevailing notion of truth or ideals. An argument can be rejected if it violates the prevailing notion of truth. Suppose, an argument is that 'Man is not social', it is not forceful because it is factually incorrect. V. Sometimes an argument supports an action on the basis of consequences which are not universally accepted and which are not logically sound. Such an argument can only be described as the assumption or individual perception of the speaker or arguer. In no case such an argument be forceful. VI. Sometimes an argument asserts something on the basis of a precedent or…

Statement and Assumption - Reasoning Video lecture in Hindi. It covers the IBPS and SBI Bank PO / Clerk Examinations. This is a Completely free study material especially designed for students preparing for IBPS SBI Bank PO / Clerk Examinations. Title : Statement and Assumption for IBPS Bank PO/ Clerk (Hindi Video) Study Material Chapter Name : Statement and Assumption Subject : Reasoning ( Verbal Reasoning ) Exams : SBI PO, IBPS PO, SBI Clerk, IBPS Clerk, IBPS RRB, RBI, LIC AAO etc. Language: Hindi (Terms in English) Format : Video Lectures Topic Covered : 1. Statement and Assumption Keywords : statement and assumption for sbi po, statement and assumption questions and answers, statement and assumption tricks in hindi, statement and assumption reasoning Brief Introduction : An assumption is something that can be supposed by the implied meanings of the given statement. Imply means to suggest or express indirectly.' Often people do not speak what is in their mind or what they think in totality, but we can infer or assume what must have in their mind from the statements made by them. For example when you say, 'An honest Police Inspector has come to the city, and so crime will be checked'. then the assumption you make is that if Police Inspector is honest, he could put a check on the crime. Thus, when we say something we do not express everything, every aspect of our ideas into words. We tend to leave many things or ideas unsaid, which may be defined as an assumption. It is that part of an argument on the basis of which we say something. Now, we can say that an assumption is that part of an argument which is not expressed or said explicitly as it is assumed or understood intrinsically. Consider the following illustration : Ex. Statement : Robert is a good player of Indian hockey team. So, India should win the match. When we analyse these statements, we can express the same idea more elaborately as : (i) Robert is a good player of Indian hockey team (ii) A good player is likely to help his team win the match. (iii) So, India may win the match. The statement (ii) is left unsaid deliberately while arguing because it is taken for granted. Hence, it is assumption. Thus, an assumption is the hidden part of an argument. In short, we can say that an assumption is something which is assumed, supposed or taken for granted. Assumption is one type of implication. If we ask a person. - Did you go from Delhi to Patna by air?", we assume that Delhi and Patna are connected by air (route) — it is the implied meaning of the statement. Therefore, an implication may be an assumption, i.e. on the basis of which we say something. Consider another example : Ex. Statement : Our country has stood like a solid rock in the face of common danger. From the statement it is implied that there have been dangers to our country— this is also an assumption. Here it should be noted that implications can also be long drawn conclusions and such conclusions are not valid assumptions. Note that there is basic difference between the assumption and implication. An assumption is something on which the statement is based. On the other hand, an implication is something which is derived from and, therefore, based upon the statement. ANALYTICAL DISCUSSION ON ASSUMPTIONS On the basis of examples cited above, one may conclude that the task of determining the validity of an assumption is not so perplexing. However a cautious and right approach is required to accomplish the task properly. Sometimes a single word/phrase makes considerable difference while determining the various facets of assumptions, we are providing some important clues which will help you to recognise a valid assumption in different context. I. The presence of certain words in the assumption makes it valid or invalid by imparting a kind of exclusiveness to the sentence. There are some words that lend a greater degree of emphasis on the sentence than some others do, thereby altering the usual implication of the sentence. Therefore, one should be careful when such words are employed in a statement Words like only, best, strongest, all, certainly etc. connote some kind of certainty and you must be able to understand their implications in a statement. Note : General statement should not be based on definitive assumption. II. Sometimes either some positive aspect or some negative aspect of a fact/report/observation/study or even data is given followed by a suggested course of action. When some negative aspect of a fact/ report/ data is mentioned, the following assumptions will be valid : (i) the fact/report/data needs improvement. (ii) the negative aspect of the fact/ report/data is harmful or undesirable. (iii) the suggested course of action will improve that situation. (iv) The adoption of suggested course of action is advantageous. Consider the following example: III. Sometimes 'cause-effect' relationship is expressed in the statement. This relationship can be expressed in different ways in…

Permutation & Combinations Calculations - Quantitative Aptitude Video lecture in Hindi. It covers the IBPS and SBI Bank PO / Clerk Examinations. This is a Completely free study material especially designed for students preparing for IBPS SBI Bank PO / Clerk Examinations. Title : Permutation & Combinations for IBPS Bank PO/ Clerk (Hindi Video) Study Material Chapter Name : Permutation & Combinations Calculations Subject : Quantitative Aptitude (Numerical Ability) Exams : SBI PO, IBPS PO, SBI Clerk, IBPS Clerk, IBPS RRB, RBI, LIC AAO etc. Language: Hindi (Terms in English) Format : Video Lectures Topic Covered : 1. What is Permutation? 2. Word Problems on Permutations 3. What is Combinations? 4. Problems on Permutation and Combinations Keywords: permutation combination basics, permutation combination aptitude questions, permutation combination bank po, permutation combination questions Brief Introduction: Factorial Notation : Let n be a positive integer. Then, the continued product of first n natural numbers is called factorial n to be denoted by n! or ⌊n . Also we define 0! = 1When n is negative or a fraction, ⌊n is not defined. Thus, according to the definition of ?n. ⌊n 1. 2. 3. .... (n - 1) n = n (n - 1) (n - 2) .... 2.1 For example, ⌊5 = 1. 2. 3. 4. 5 = 5. 4. 3. 2. 1 = 120 Clearly, ⌊n = 1. 2. 3. 4 .... (n - 2), (n - 1) n = {1. 2. 3 ........(n - 2) (n - 1)} n For example, ⌊7 = 2. 3. 4. 5. 6. 7 = (1. 2. 3. 4. 5. 6).7 = ⌊6 . 7 = 7 ?6 If r and n are positive integers and r <n GROUPS OR SELECTIONS I. Let us consider 4 persons whose names are A, B, C and D. Now two persons whose names are A and C together form a group namely AC or CA. Note that group AC consists of two persons whose names are A and C and group CA consists of two persons whose names are C and A. Thus AC and CA represent the same group since they contain the same two persons A and C. Thus it is clear that the order of appearance of the two persons in the group does not change the constitution of the group. Thus we see that in the case of groups, the order of objects is immaterial and we are simply interested in the selection of desired things or objects without any consideration of their order. II. Suppose we have three digits 1, 2 and 3 and we like to know the groups of two digits out of these three digits. These groups are (i) (1, 2) or (2, 1) (11) (1, 3) or (3, 1) (iii) (2, 3) or (3, 2) Thus, there will be three groups of 2 digits formed by choosing two out of the three digits 1, 2 and 3. In other words, we can also say that the number of selections of two digits from among the three digits (numbers) 1, 2, 3 is 3 namely (1, 2) or (2, 1), (1, 3) or (3, 1) and (2, 3) or (3, 2). Hence, groups are also called selections. Arrangement : Let there be three distinct objects namely A, B and C. The possible groups that can be formed out of three taken two at a time are (i) AB (ii) BC (iii) AC. Clearly three such groups are possible. Now, the two objects in each of these groups can be arranged in two different ways namely (i) AB and BA (ii) BC and CB (iii) AC and CA. Thus in all there are 6 such arrangements of three different objects taken two at a time. Clearly, number of arrangements = Number of groups ×?r where r is the number of objects in each group. In the above example, number of arrangements = number of groups or selections x ⌊2 = 3 × ?2 = 6 Thus, we see that in case of arrangement change of position of objects causes change in the arrangement. PERMUTATIONS Definition : Each of the different arrangements which can be made by taking some or all of a number of given things or objects at a time is called a permutation. Note : It should be noted that in permutations the order of arrangements is taken into account, when the order is changed, a different permutation is obtained. The symbol nPr : The symbol nPr, denotes the number of permutations of n different things taken r at a time. The letter P stands for permutations. Thus the symbol 5P2 will denote the number of permutations or arrangements of 5 different things taken 2 at a time. COMBINATIONS Definition : Each of the different groups or selections which can be made by taking some or all of a number of given things or objects at a time is called a combination. The symbol nCr : The symbol nCr denotes the number of combinations of n different things taken r at a time. The letter C stands for combination. Thus, the symbol 5C2 will denote the number of combinations or selections of 5 different things taken 2 at a time. Remark : In combination or selection order of things is not taken into account. We have already pointed out that Number of arrangements =?r (number of selections or groups) where r is the no. of objects in each group. Difference between Permutation and Combination (i) In a combination only selection is made whereas in a permutation not only a selection is made but also an arrangement in a definite order is taken into consideration. (ii) In a combination, the ordering…

Mixture and Allegations Calculations - Quantitative Aptitude Video lecture in Hindi. It covers the IBPS and SBI Bank PO / Clerk Examinations. This is a Completely free study material especially designed for students preparing for IBPS SBI Bank PO / Clerk Examinations. Title : Mixture and Allegations for IBPS Bank PO/ Clerk (Hindi Video) Study Material Chapter Name : Mixture and Allegations Calculations Subject : Quantitative Aptitude (Numerical Ability) Exams : SBI PO, IBPS PO, SBI Clerk, IBPS Clerk, IBPS RRB, RBI, LIC AAO etc. Language: Hindi (Terms in English) Format : Video Lectures Topic Covered : 1. Concept of Mixture and Allegations and Some Basic Problems 2. Some Practice Problems 3. Some High Level Problems for Examinations 4. Applications for the Concept of Mixture and Allegations 5. Previous Year Problems of SSC-CGL Keywords: mixture and allegations tricks, mixture and allegations formula, mixture and allegations questions, mixture and allegations problems IMPORTANT POINTS 1. The literal meaning of the word 'Alligation' is 'linking'. 2. As a matter of fact, alligation may be understood as a rule that enables us (i) to find out the mean or average value of mixture when the prices of two or more ingredients which may be mixed together and the proportion in which they are mixed are given. This is known as 'Alligation Medial'. (ii) to find out the proportion in which two ingredients of the same nature of given prices should be mixed so as to produce a mixture worth a desired price. This is known as 'Alligation Alternate'. It should be noted that the value of the mixture can't be lower than the cheaper value and higher than the dearer. Alligation Rule. Statement : The two ingredients should be mixed in the inverse ratio of the differences of the two given prices and the mean price. Mathematically, we can express this rule as below : We represent it as Note : C.P. of unit quantity of the mixture is called the mean price. Explanation of Alligation Rule : We may very well understand the above rule with the help of an example given below : Example. In what ratio should ghee worth Rs. 30 per kg and ghee worth Rs. 45 per kg. be mixed so as to get a mixture worth Rs. 40 per kg? Solution . The price per kg. of cheaper ghee is Rs. 10 less than the rate of the mixture. The price per kg. of dearer ghee is Rs. 5 more than the rate of the mixture. Hence it is obvious that every 1 kg. of cheaper ghee will result in a profit of Rs. 10 and every 1 kg of dearer ghee will result in a loss of Rs. 5. If we wish to have the mixture worth the desired rate, then the profit and loss should equalise, i.e., the gain on cheaper ghee must be equal to the loss on the dearer ghee so that there will be neither gain or loss by selling the mixture at Rs. 45/kg. Hence the two ghee's should be mixed in the ratio of 1 : 2. Thus the alligation rule is established. Let us consider the following question asked in previous exam. A grocer purchased 2 kg. of rice at the rate of Rs. 15 per kg. and 3 kg. of rice at the rate of Rs. 13 per kg. At what price per kg. should he sell the mixture to earn % profit on the cost price ? (1) Rs. 28.00 (2) Rs. 20.00 (3) Rs. 18.40 (4) Rs. 17.40 (5) None of these Solution : (3) Mixture : 2 kg of rice at Rs. 15/kg + 3 4 of rice at Rs. 13/kg Total weight = 2 + 3 = 5 kg Total cost price = (2 × 15) + (3 × 13) = 30 + 39 = Rs. 69 Cost price per kg of the mixture Selling price to get % profit A shopkeeper bought three varieties A, B and C of rice in different amounts at the rates of Rs. 34.50, Rs. 28.60 and Rs. 32.40 per kg respectively. In which of the following transactions he will gain maximum ? (1) He bought 20 kg of rice of varieties A and C each and sold at Rs. 38 and Rs. 36 per kg respectively (2) He bought 30kg of rice of variety A and sold at Rs. 37 per kg and he bought 40 kg of variety B and sold at Rs. 33 per kg. (3) He bought 20 kg of rice of variety B and sold at Rs. 40 per kg and he bought 40 kg of variety C and sold at Rs. 38 per kg. (4) He bought 25 kg of rice of variety C and sold at Rs. 42 per kg and he bought 30 kg of variety A and sold at Rs. 38 per kg. (5) He bought 40 kg of rice of variety B and sold at Rs. 37 per kg and he bought 20 kg of variety A and sold at Rs. 40 per kg. Solution : (5) The wheat sold by a grocer contained 10% low quality wheat. What quantity of good quality wheat should be added to 150 kgs of wheat so that the percentage of low quality wheat becomes 5% ? (1) 150 kgs (2) 135 kgs (3) 50 kgs (4) 85 kgs (5) None of these kgs. = 150kg.

Time and Work Calculations - Quantitative Aptitude Video lecture in Hindi. It covers the IBPS and SBI Bank PO / Clerk Examinations. This is a Completely free study material especially designed for students preparing for IBPS SBI Bank PO / Clerk Examinations. Title : Time and Work for IBPS Bank PO/ Clerk (Hindi Video) Study Material Chapter Name : Time and Work Calculations Subject : Quantitative Aptitude (Numerical Ability) Exams : SBI PO, IBPS PO, SBI Clerk, IBPS Clerk, IBPS RRB, RBI, LIC AAO etc. Language: Hindi (Terms in English) Format : Video Lectures Topic Covered : 1. Basic Concepts related to Time and Work 2. Problems: When Worker is on Leave 3. Problems based on Efficiency 4. Problems Based on Men, Women and Children 5. Alternate Days and Contractor Based Problems 6. Problems based on Work and Wages 7. Pipes and Cisterns 8. Some Additional Problems Keywords: time and work questions for bank po, time and work all type of questions, time and work basic problems, time and work questions in hindi Brief Introduction: SOME IMPORTANT POINTS Certain general rules are given below. The candidates will fmd them quite useful while solving problems related to Time and Work. While solving problems related to Time and Work we have to compare the work of several working agents (men, women on children). To solve this purpose, we need find out the amount of work done by each agent in a common unit time. This unit time is generally taken as an hour, one minute or one day depending upon the nature of the problem. The total work is assumed to be 1. If one can do a piece of work in 15 days, then it means that he can do of work in 1 day. Conversely, if one can do work in 1 day, it implies that he can complete the work in 15 days. One day's work = 1/ No. of days required to finish the work No. of days required to finish the work = 1/ One day's work If A does of work in 1 day and B does of the same work in 1 day then A + B together will do of that work in 1 day . If A is thrice as good as a workman as B then A's work : B's work = 3 : 1 and ratio of the times taken by A and B to complete the work = 1 : 3 i.e. A will take of the time taken by B to complete that work. The time required to complete a certain piece of work is increased (or decreased) in the same ratio in which the number of men engaged to do that piece of work is decreased (or increased). For example, if the number of men engaged to do a piece of work be changed in the ratio 4 : 5, the time required to complete that piece of work will change in the ratio 5 : 4. Time and number of men each are always in direct proportion to work. All the above points can be summarised as given below : If 'M1' persons can do 'W1' works in 'D1' days and 'M2' persons can do 'W2' works in 'D2' days then we have a yew general formula in the relationship of M1 D1 W2 = M2D2W1 It is an all in one formula and basic formula. We can also conclude that I. More men less days and conversely more days less men. II. More men more work and conversely more work more men. III. More days more work and conversely more work more days. If 'A' can do a piece of work in x days and 'B' can do it in y days then 'A' and 'B' working together can do the same work in Days. If A, B and C can do a work in x, y and z days respectively then all of them working together can finish the work indays. PIPES AND CISTERN The method of solving the questions on pipes and cistern is almost same as that of solving the questions of Time and Work, but with a bit difference as negative work comes into play due to leakage of pipes and cistern. Important Points : Inlet : A pipe connected with a cistern or a tank or a reservoir that fills it is known as inlet. Outlet : A pipe connected with a tank or a cistern or a reservoir to empty it, is known as an outlet. Important Formulae. 1. If a pipe can fill a tank in x hours then part of tank filled in 1 hour 2. If a pipe can empty a full tank in y hours, then part of tank emptied in 1 hour = 3. If a pipe can fill a tank in x hours and another pipe can empty the full tank in y hours (where y > x), then on opening both the pipes at the same time, the net part filled in 1 hour Let us consider the following question asked in previous exam. 1. 12 men take 36 days to do a work while 12 women complete of the same work in 36 days. In how many days 10 men and 8 women together will complete the same work? (1) 6 (2) 27 (3) 12 (4)Data inadec.-aze (5) None of Solution : (2) Clearly, 9 × 360 children = 18 × 72 men = 12 × 162 women ⇒ 45 children = 18 men = 27 women 5 children = 2 men = 3 women Now, 4 men + 12 women + 10 children = 4 men + 8 men + 4 men = 16 men 18 men can complete the work in 72 days. ∴ 16 men can complete the work in 3. 12 men can complete a piece of work in 36 days. 18 women can complete the same piece of work in 60 days. 8 men and 20 women work together for 20 days. If only women were to complete the remaining piece of work in 4 days, how many women…
