2. Each question given has a problem and two statements numbered 1 and 2 giving certain information. You have to decide if the information given in the statements is sufficient for answering the problem. Indicate your answer A.Statement 1 alone is sufficient, but statement 2 alone is not sufficient to answer the question B.Statement 2 alone is sufficient ,but statement 1 alone is not sufficient to answer the question C.Both statement taken together are sufficient to answer the question,but neither statement alone is sufficient. D.Each statement alone is sufficient E.Statements 1 and 2 together are not sufficient, and additional data is needed to answer the question. What is the ratio of male to female officers in the police force in town? 1 The number of female officers is 250 less the half the number of male officers 2The number of female officers 1/7 the number of male officers A.statement 1 alone is sufficient, but statement 2 alone is not sufficient to answer the question B.statement 2 alone is sufficient, but statement 1 alone is not sufficient to answer the question C.both statements taken together are sufficient to answer the question, but neither statement alone is sufficient D.each statement alone is sufficient
Answer: B
Explanation: To get the ratio we need total numbers male to total numbers female. There is not enough information in (1), so A and D cannot be correct. A ratio is just a fraction, so if we have the fraction of female officers we have the ratio (assuming that all officers have to be either male or female!!!). So the answer is B.
3. What is the value of n? 1.3n + 2m = 18 2.n – m = 2n – (4 + m) A.statement 1 alone is sufficient, but statement 2 alone is not sufficient to answer the question B.Should have chose statement 2 alone is sufficient, but statement 1 alone is not sufficient to answer the question C.both statements taken together are sufficient to answer the question, but neither statement alone is sufficient D.Each statement alone is sufficient
Answer: B Explanation: Statement (1) can have a variety of solutions (n could be 2, or 4 or a fractional number or negative etc. etc.), so the answer cannot be A or D. Looking at (2) on its own we should at least take out the brackets before we decide whether or not it can be solved. So we get n – m = 2n - 4 – m and then we can add m to both sides to give n = 2n – 4. In other words we have solved the equation (n = 4) and the answer is B.
4. How long did it take Henry to drive to work last Wednesday? (He did not stop on the way). 1.If he had driven twice as fast he would have taken 35 minutes. 2.His average speed was 30 miles per hour.
A.statement 1 alone is sufficient, but statement 2 alone is not sufficient to answer the question B.statement 2 alone is sufficient, but statement 1 alone is not sufficient to answer the question C.both statements taken together are sufficient to answer the question, but neither statement alone is sufficient D.each statement alone is sufficient
Answer: A
Explanation: Don’t overcomplicate this one! From statement (1) we can directly say that if he had driven at his normal speed he would have taken twice the time (i.e. 70 minutes). So the answer must be A or D. Looking at (2) alone we have speed but not distance and so we cannot get time. The answer is A.
5. What is the slope of line l which passes through the origin of a rectangular coordinate system? 1.The line does not intersect with the line y = x + 2 2.The line passes through the point (3,3) A.statement 1 alone is sufficient, but statement 2 alone is not sufficient to answer the question B.statement 2 alone is sufficient, but statement 1 alone is not sufficient to answer the question C.both statements taken together are sufficient to answer the question, but neither statement alone is sufficient D.Each statement alone is sufficient
Answer: D Explanation: If a straight line passes through the origin we only need one other point to fix the line. And so we should note that (2) gives us one point and the answer must be B or D. Considering (1) alone, if two lines do not intersect, they must be parallel (have the same slopes). In the equation for a straight line y = mx + c, m is the slope. In this case m = 1 and we have answered the question. The answer is D.
6. If x and y are both positive integers, how much greater is x than y ? 1.x + y = 20 2.x = y²
A.statement 1 alone is sufficient, but statement 2 alone is not sufficient to answer the question B.statement 2 alone is sufficient, but statement 1 alone is not sufficient to answer the question C.both statements taken together are sufficient to answer the question, but neither statement alone is sufficient D.each statement alone is sufficient
Answer: C
Explanation: Considering (1) alone, there are many pairs of positive integers that fit the equation (19 and 1; 18 and 2 etc.) and so the answer cannot be A or D. Considering (2) alone there are many pairs of numbers that fit the expression (1,1; 4, 2; 16,4 etc.) and so the answer cannot be B. Putting the information together we can solve the problem. First we can get x = 20-y from (1) which we can substitute in the rearranged form of (2): that is 0 = y² – x to give the quadratic expression 0 = y² – 20 + y. Solving this (no need to bother) will give two solutions but only one will be positive, so the answer is C.
7. Fifty percent of the articles in a certain magazine are written by staff members. Sixty percent of the articles are on current affairs. If 75 percent of the articles on current affairs are written by staff members with more than 5 years experience of journalism, how many of the articles on current affairs are written by staff members with more than 5 years experience? 1.20 articles are written by staff members. 2.Of the articles on topics other than current affairs, 50 percent are by staff members with less than 5 years experience.
A.statement 1 alone is sufficient, but statement 2 alone is not sufficient to answer the question B.statement 2 alone is sufficient, but statement 1 alone is not sufficient to answer the question C.both statements taken together are sufficient to answer the question, but neither statement alone is sufficient D.each statement alone is sufficient
Answer: A
Explanation: There is only one item of information in (1), but we can combine it with the given information to find that the total number of articles is 40. Further we can see that 24 are on current affairs, of which 18 are by experienced staff members. So the answer must be A or D. Ignoring (1), we can see that the information in (2) gives us a fraction and not a number and no amount of trying will get us one definite number from which we can find a discrete answer. Hence the answer is A. 8. Is xy > 0 ? 1.x/y < 0 2.x + y < 0
A.statement 1 alone is sufficient, but statement 2 alone is not sufficient to answer the question B.statement 2 alone is sufficient, but statement 1 alone is not sufficient to answer the question C.both statements taken together are sufficient to answer the question, but neither statement alone is sufficient D.each statement alone is sufficient
Answer: A
Explanation: If xy is greater than zero, then either both x and y must be negative, or both must be positive. In statement (1) we have x/y shown as a negative fraction, so either x or y (but not both) must be negative. Hence xy cannot be positive. Since we have a definite solution, the answer must be A or D. Looking at (2) alone, we can see that x and y could both be negative, but it is also possible that one could be negative and the other positive depending on the absolute values of the numbers. Hence the answer is A.
9. One number, n, is selected at random from a set of 10 integers. What is the probability that ½ n + 13 = 0 ? 1.The largest integer in the set is 13. 2.The arithmetic mean of the set is zero.
A.statement 1 alone is sufficient, but statement 2 alone is not sufficient to answer the question B.statement 2 alone is sufficient, but statement 1 alone is not sufficient to answer the question C.both statements taken together are sufficient to answer the question, but neither statement alone is sufficient D.each statement alone is sufficient E.statements 1 and 2 together are not sufficient, and additional data is needed to answer the question
Answer: E
Explanation: Statement (1) alone tells us the largest number in the set. If that happened to be the number picked, then we would be certain that ½ n + 13 was not less than or equal to zero. However, we have insufficient information on the other numbers in the set. (If for example -26 was in the set, and the number picked happened to be -26, then we are certain that the value of the expression would be zero.) And so the answer cannot be A or D. From (2) alone we know that some of the numbers must be positive and some negative, but once again, we have no information on the actual numbers. (Do not assume that the smallest number has to be -13). Thus B cannot be the answer. Combining the information is also not sufficient to get the answer because we do not know what the smallest number is. The answer is E.
10. Is w an integer? 1.3w is an odd number. 2.2w is an even number.
A.statement 1 alone is sufficient, but statement 2 alone is not sufficient to answer the question B.statement 2 alone is sufficient, but statement 1 alone is not sufficient to answer the question C.both statements taken together are sufficient to answer the question, but neither statement alone is sufficient D.each statement alone is sufficient
Answer: B
Explanation: If w happened to be 1, then 3w would be an odd number, but we can pick a fraction such as 5/3 for w which also makes 3w an odd number. So the answer cannot be A or D. However, in statement (2) we are told that twice the number is even. All even numbers when divided by 2 will give us whole numbers, and so the answer is B.
11. A piece of string 1½ meters long is cut into three pieces. What is the length of each of the pieces? 1.The length of one of the pieces is 20 cm. 2.The sum of the lengths of two of the pieces is equal to the length of the third piece.
A.statement 1 alone is sufficient, but statement 2 alone is not sufficient to answer the question B.statement 2 alone is sufficient, but statement 1 alone is not sufficient to answer the question C.both statements taken together are sufficient to answer the question, but neither statement alone is sufficient D.each statement alone is sufficient
Answer: C
Explanation: Considering statement (1) we cannot get information on the other two parts of the string. Thus the answer cannot be A or D. From (2) we can write the equation x + y =z, and we know that x + y + z = 150, but we cannot get any further, and so the answer cannot be B. Now if we take the information in both statements we can see that 20cm cannot be the length of the longest piece (z) and so in our equations we can call it x or y. Now our equations can be solved because we have two equations and two unknowns. (x + 20 = z; and x + 20 + z =150. hence x + 20 + x + 20 =150, and x = 55). There was no need to solve. Also we should have spotted that since x + y is equal to z,then z is half the string (75cm) and x + y is the other half, so once we have either x or y, we have the solution. Hence answer C
12. There are 120 saplings to be planted in an orchard. Ben and Sue working together without a break can complete the job in six hours. How long would it take Ben working alone to complete the job? 1.Sue plants 3 saplings in the time it takes Ben to plant 2. 2.Sue working alone would take 10 hours to do the job.
A.statement 1 alone is sufficient, but statement 2 alone is not sufficient to answer the question B.statement 2 alone is sufficient, but statement 1 alone is not sufficient to answer the question C.both statements taken together are sufficient to answer the question, but neither statement alone is sufficient D.each statement alone is sufficient
Answer: D
Explanation: From (1) we know how much faster Sue works than Ben does. So we know that of the 120 saplings 48 would be planted by Ben and 72 by Sue. So we know that Ben plants 48/6 = 8 saplings per hour and we can work out how long it would take for 120. Hence the answer must be A or D. From statement (2) we can get the fraction of the job that Sue does per hour and hence the fraction of the job that she did in six hours. Hence we can work out how much of the job Ben did in six hours, and the fraction he would do per hour. Thus we can get the time it would take him alone. And so the answer is D.

27. It is not luck but labour that makes man. Luck, says an American Writer, is ever waiting for something to turn up; labour with keen eyes and strong will always turns up something. Luck lies in bed andwishes the postman would bring him news of legacy ; labour turns out at sixand with busy pen ringing hammer lays the foundation of competence . Luck whines, labour watches. Luck slips downwards to self-indulgence; labour strides upwards and aspires to independence. The conviction therefore, is extending that diligence is the mother of good luck. In other words that a man's success in life will be proportionate to his efforts, to hisindustry, to his attention to small things. 42.Which one of the following statements sumps up the meaning of the passage ?
A.Luck waits without exertion, but labour exerts without waiting. B.Luck is self-indulgent but labour is selfless. C.Luck waits and complains without working while labour achieves although it complains D.Luck often ends in defeat, but labour produces luck.
Answer: D
Explanation: It can be derived through inference .Elimination will also help. (a) and (b) are eliminated easily on the basis of information . c) and d) are of a general nature, but you may come to the right conclusion by arguing that labour is not always selfless. One does hard labour for a purpose. Again, remember the general hint that you should prefer choice in such cases which includes the largest possibility.
28. Which one of the following words in the passage indicate that the writer does not ultimately reject the element of luck?
A.' Luck ......is ever waiting'. B.' Luck whines' C.Diligence is the mother of good luck D.Luck ... wishes the postman would bring him news.
Answer: C
Explanation: The answer can be arrives at by simple inference. This is the implication of the passage as well.
29. Which of the following statements is true about the following passage?
A.Luck is necessary for success. B.Sucess depends only on hard luck. C.Expectation of good luck always meets with disappointment. D.Success is exactly proportionate to hard work.
Answer: D
Explanation: The information is in the last sentence.30. '...... Labour turns out at six and with busy pen ringing hammer lays the foundation of competence '. what does this statement mean?
A.Hard work of all kinds make people efficient. B.Labour lays the foundation of the building. C.The writer and the labourer are the true eyes of the society. D.There is no worker who works so hard as the labourer who begins his day at six in the morning.
Answer: A
Explanation: The information given in the middle of the passage and simple inference will help. The reference to both pen and hammer implies that the meaning here includes all kinds of work. The pen stands for mental work and hammer for the physical labour.
