The total of the ages of Amar, Akbar and Anthony is 80 years. What was the total of their ages three years ago?

            (a) 71 years                  (b) 72 years

            (c) 74 years                  (d) 77 years

Two bus tickets from city A to B and three tickets from city A to C cost Rs. 77 but three tickets from city A to B and two tickets from city A to C cost Rs. 73. What are the fares for cities B and C from A?

            (a) `4, Rs23                  (b) `13, Rs17

            (c) `15, Rs14                (d) `17, Rs13

Sol.      (b) Let Rs. x be the fare of city B from city A and Rs. y be the fare of city C from city A. Then,

2x + 3y = 77 …(i)

3x + 2y = 73 …(ii)

Multiplying (i) by 3 and (ii) by 2 and subtracting, we get: 5y = 85 or y= 17. Putting y = 17 in (i), we get : x = 13.


A student got twice as many sums wrong as he got right. If he attempted 48 sums in all, how many did he solve correctly?

            (a) 12                           (b) 16

            (c) 18                           (d) 24

Sol.      (b) Suppose the boy got x sums right and 2x sums wrong. Then, x ÷ 2x = 48, 3x = 48, x = 16.


In a group of cows and hens, the number of legs are 14 more than twice the number of   heads. The number of cows is

            (a) 5                             (b) 7

            (c) 10                           (d) 12

Sol.      (b) Let the number of cows be x and the number of hens be y.

            Then, 4x + 2y = 2 (x + y) + 14, 4x+2y = 2x+2y +14, 2x= 14, x =7.
