1 McAfee Aptitude Paper 1. Out of the three numbers A, B and C, A exceeds B by 20 and C exceeds A by 55. If the sum of all the numbers is 230, What is the difference between the largest and the smallest number? A. 52 B. 58 C. 63 D. 75 We have, A = B + 20 & C = A + 55 = B + 75 Thus, (B + 20) + (B) + (B + 75) = 230 B = 45 Thus, A = 65 & C = 120. Hence, (C) (B) = = A motorboat in still water travels at speed of 36 kmph. It goes 56 km upstream in 1 hour 45 minutes. The time taken by it to cover the same distance down the stream will be: A. 2 h, 25 min. B. 3 h C. 1 h, 24 min. D. 2 h, 21 min. 1 hour 45 minutes = 1+(45/60) = 7/4 hours. Speed of the motorboat up-stream, = Distance /time taken = 56 km /(7/4)h = 56*4/7 = 32 kmph Let the speed of the current = x kmph Hence, 36-x = 32 Or, x = = 4 kmph Speed of boat down the stream = 36+4 = 40 kmph. Time taken to cover 56 km at 40 km/h = 56/40 = 7/5 hours = 1 hour 24 minutes. 3. Five years ago, the average age of A, B, C and D was 45 yr. with E joining them now, the average of all the five is 49 yr. How old is E? A. 25 yr. B. 40 yr. C. 45 yr. D. 64 yr. Total present age of A, B, C and D, = (45*4) +(4*5) = 200 yr.; Total age present age of A, B, C, D and E, = 49*5 = 245 yr. So, age of E = 45 yr. 4. Sam purchased 20 dozens of toys at the rate of Rs. 375 per dozen. He sold each one of them at the rate of Rs. 33. What was his percentage profit? A. 3.5 B. 4.5

2 C. 5.6 D. 6.5 Cost Price of 1 toy = Rs. 375/12 = Rs Selling Price of 1 toy = Rs. 33 So, Gain = Rs. ( ) = Rs Profit % = (1.75/31.25 x 100) % = 28 % = 5.6%. 5. The average age of A, B, C, D and E is 40 years. The average age of A and B is 35 years and the average of C and D is 42 years. Age of E is: A. 48 B. 46 C. 42 D. 45 According to the question, => A+B+C+D+E = 40*5 = 200 => A+B = 35*2 = 70 => C+D = 42*2 = 84 Therefore, E = (A+B+C+D+E) -(A+B+C+D) = = 46 years. 6. The population of a town increased from 1,75,000 to 2,62,500 in a decade. The average percent increase of population per year is: A. 4.37% B. 5% C. 6% D. 8.75% Increase in 10 years = ( ) = Increase% = (87500/ x 100) % = 50%. Required average = 50/10 % = 5%. 7. Two pipes A and B can fill a tank in 15 minutes and 20 minutes respectively. Both the pipes are opened together but after 4 minutes, pipe A is turned off. What is the total time required to fill the tank? A. 10 min. 20 sec. B. 11 min. 45 sec. C. 12 min. 30 sec. D. 14 min. 40 sec. Part filled in 4 minutes = 4(1/15 + 1/20) = 7/15. Remaining part = (1-7/ 15) = 8/15. Part filled by B in 1 minute = 1/20.'. 1/20: 8/15::1:x => x = 8/15 x 1 x 20 = 32/3 = 10 min. 40 sec..'. The tank will be full in (4 min min sec.) = 14 min. 40 sec. 8. From a pack of 52 cards, two cards are drawn together, what is the probability that both the cards are kings? A. 2/121

3 B. 2/221 C. 1/221 D. 1/13 Total cases = 52C2 = (52*51)/ (2*1) = 1326 Total King cases = 4C2 = 4*3/2*1 = 6. Hence, the required Probability = 6/1326 = 1/ Sachin is younger than Rahul by 7 years. If their ages are in the respective ratio of 7: 9, how old is Sachin? A. 16 years B. 18 years C. 28 years D years E. None of these Let Rahul's age be x years. Then, Sachin's age = (x - 7) years..'. (x - 7)/x = 7/9. => 9x - 63 = 7x. => 2x = 63 => x = 31.5 Hence, Sachin's age = (x - 7) = 24.5 years. 10. There are 8 men and 10 women and you need to form a committee of 5 men and 6 women. In how many ways can the committee be formed? A B. 11 C D. None of these We need to select 5 men from 8 men and 6 women from 10 women Number of ways to do this => 8C5 10C6 => 8C3 10C4 [ ncr = nc(n-r)] => [(8*7*6)/(3*2*1)]*[(10*9*8*7)/(4*3*2*1)] => => McAfee Logical Reasoning Test 11.

6 Some religious teachers have taught that Man is made up of a body and a soul: But they have been silent about the Intellect. Their followers try to feed the body on earth and to save soul from perdition after death: But they neglected the claims of the mind. Bread for the body and Virtue for the soul: These are regarded as the indispensable requisites of human welfare here and hereafter. Nothing is said about knowledge and education. Thus Jesus Christ spoke much of feeding the hungry, healing the sick, and converting the sinners: But he never taught the duty of teaching the ignorant and increasing scientific knowledge. He himself was not a well-educated man, and intellectual pursuits were beyond his horizon. Gautam Buddha also laid stress on morality, meditation and asceticism, but he did not attach great importance to history, science, art or literature. St. Ambrose deprecated scientific studies and wrote, Tel discuss the nature and position of the earth does not help us in our hope for life to come. St. Basil said very frankly and foolishly, It is not a matter of interest for us whether the earth is a sphere or a cylinder or disc. Thomas Carlyle also followed the Christian traditions when he declared that he honored only two men and no third: The manual labor and the religious teacher. He forgot the scientist, the scholar and the artist. The cynics of Greece despised education at last? 21. What have the religious teachers taught in the past? A. That man is made up of body only B.
