 1. If 40% of a number is equal to two-third of another number, what is the ratio of the first number to the second number? Answer: 5:3 Solution: Let the numbers be x,y. 40x/100 = 2y/3, x/y = (2*100)/(3*40), x/y = 5/3 2. Two numbers are in the ratio of 3 : 4. If 5 is subtracted from each, the resulting numbers are in the ratio 2 : 3. Find the numbers. Answer: 15.20 Solution: Let the numbers be 3x,4x. 3x-5:4x-5 = 2:3, 9x-15 = 8x-10, x=5. So the numbers are 15,20 3. If a=5b=2c=4d, then a:b:c:d is Answer: 20:4:10:5 Solution: a/b = 5/1, b/c = 2/5, c/d = 2/1 (4/2 which is 2/1) a:b:c:d = n1*n2*n3 : d1*n2*n3 : d1*d2*n3 : d1*d2*d3 = 5*2*2 : 1*2*2 : 1*5*2 : 1*5*1 = 20:4:10:5 4.

  1. A bomber drops 4 bombs to destroy a target. Two bombs are enough to destroy the target. If the chance of a bomb hitting the target is 0.4, find the probability that the target is not destroyed. Answer: 297/625 Solution: Probability of a bomb hitting the target = 0.4 = 2/5, not hitting = 3/5 The target is not destroyed only when just one or no bomb hits it. Probability that all bombs miss = (3/5)^4 = 81/625 Probability that just one bomb hits = 4C1 * (2/5) * (3/5)^3 = 216/625 Probability that the target is NOT destroyed = 81/625 + 216/625 = 297/625 2. A classroom has 3 electric bulb holders. From a collection of 10 bulbs of which 4 are defective, 3 are selected at random and put in the holders. Find the probability that all bulbs are glowing.

In how many ways can a playiing eleven be selected if we have to select 1 forward keeper and at least 4 mid-fielders? Answer: None of these Solution: Ans: None of the above (As answer is 1092) Num of ways of selecting a forward = 2C1 = 2. Atleast 4 mid-fielders means it can be 4 or also 5. When it is 4 mid-fielders, Num of ways to pick the team = 2C1 * 5C4 * 9C6 = 2*5*84 = 840 When it is 5 mid-fielders, Num of ways to pick the team = 2C1 * 5C5 * 9C5 = 2*1*126 = 2
