ANS:D - None of these

Let R, G and B represent the number of balls in red, green and blue boxes respectively.Then, .R + G + B = 108 ...(i),G + R = 2B ...(ii)B = 2R ...(iii)From (ii) and (iii), we have G + R = 2x 2R = 4R or G = 3R.Putting G = 3R and B = 2R in (i), we get:R + 3R + 2R = 108 6R = 108 R = 18.Therefore Number of balls in green box = G = 3R = (3 x 18) = 54.

ANS:D - 20

Total runs scored = (36 x 5) = 180.Let the runs scored by E be x.Then, runs scored by D = x + 5; runs scored by A = x + 8;runs scored by B = x + x + 5 = 2x + 5;runs scored by C = (107 - B) = 107 - (2x + 5) = 102 - 2x.So, total runs = (x + 8) + (2x + 5) + (102 - 2x) + (x + 5) + x = 3x + 120.Therefore 3x + 120 =180 3X = 60 x = 20.

ANS:B - 990

Explanation: Total number of digits = (No. of digits in 1- digit page nos. + No. of digits in 2-digit page nos. + No. of digits in 3- digit page nos.) = (1 x 9 + 2 x 90 + 3 x 267) = (9 + 180 + 801) = 990.

ANS:B - 3

Explanation: Let d and s represent the number of daughters and sons respectively. Then, we have : d - 1 = s and 2 (s - 1) = d. Solving these two equations, we get: d = 4, s = 3.

ANS:A - 60

ANS:A - 23 years

Explanation: Ayush's present age = 10 years. His mother's present age = (10 + 20) years = 30 years. Ayush's father's present age = (30 + 5) years = 35 years. Ayush's father's age at the time of Ayush's birth = (35 - 10) years = 25 years. Therefore Ayush's father's age at the time of marriage = (25 - 2) years = 23 years.

ANS:B - 16

Suppose the boy got x sums right and 2x sums wrong. Then, x + 2x = 48 3x = 48 x = 16.

ANS:C - 30

ANS:A - 25

Explanation: Clearly, the required number would be such that it leaves a remainder of 1 when divided by 2, 3 or 4 and no remainder when divided by 5. Such a number is 25.
