Q-3) In a 4000 meter race around a circular stadium having a circumference of 1000 meters, the fastest runner and the slowest runner reach the same point at the end of the 5 th minute, for the first time after the start of the race. All the runners have the
same staring point and each runner maintains a uniform speed throughout the race. If the fastest runner runs at twice the speed of the slowest runner, what is the time taken by the fastest runner to finish the race?

(a) 20 min (b) 15 min © 10 min (d) 5 min

Answer — c) 10 min

Q-4) There are 4 quarts in a gallon. A gallon of petrol sells for Rs.12 and a quart of the same petrol sells for Rs.5. The owner of a rental agency has 6 machines and each machine needs 5 quarts of petrol. What is the minimum amount of money he must spend to purchase enough petrol?

(a) Rs.84 (b) Rs.94 © Rs.96 (d) Rs.102

Answer — b) 94 — Total oil needed = 6 × 5 = 30 quarts = 7 gallons and 2 quarts. [ Since, 7 x 4 = 28 + 2 ]

∴ The cost of oil/quart is cheaper when you purchase by the gallon, he should buy at least 7 gallons of oil. However, in order to get the remaining 2 quarts, it is cheaper to buy 2 quarts individually rather than another gallon. ∴ The minimum amount = 7 × Rs.12 + 2 × Rs.5 = Rs.94.

Q-7) How many even integers n, where 100 ≤ n ≤ 200, are divisible neither by seven nor by nine?

(a) 39 (b) 37 © 40 (d) 38

Answer — a) 39 — There are 101 integers in all, of which 51 are even. From 100 to 200, there are 14 multiples of 7, of which 7 are even. There are 11 multiples of 9, of which 6 are even. But there is one integer (i.e. 126) that is a multiple of both 7 and 9 and also even. Hence the answer is (51–7–6 + 1) = 39

Q-13) A shepherd has 1 million sheep at the beginning of Year 2000. The numbers grow by x% (x > 0) during the year. A famine hits his village in the next year and many of his sheep die. The sheep population decreases by y% during 2001 and atthe beginning of 2002 the shepherd finds that he is left with 1 million sheep. Which of the following is correct?

(a) x > y (b) y > x © x = y (d) Cannot be determined

Answer — a) x>y — Let us assume the value of x to be 10%.

Therefore, the number of sheep in the herd at the beginning of year 2001 (end of 2000) will be 1 million + 10% of 1 million = 1.1 million In 2001, the numbers decrease by y% and at the end of the year the number sheep in the herd = 1 million.
i.e., 0.1 million sheep have died in 2001. In terms of the percentage of the number of sheep alive at the beginning of 2001, it will
be (0.1/1.1)×100 % = 9.09%. From the above illustration it is clear that x > y.

Q-15) The numbers {1, 3, 6, 7, 7, 7} are used to form three 2-digit numbers. If the sum of these three numbers is a prime number p, what is the largest possible value of p?

(a)211 (b)151 © 219 (d) 209

Answer — a) 211 — What is the largest possible sum of these three numbers that we can form? Maximize the first digit: 76+73+71=220=even, so not a prime. Let’s try next largest sum, switch digits in 76 and we’ll get: 67+73+71=211=prime.
