Arithmetic Reasoning
1. Reena is twice as old as Sunita. Three years ago, she was three times as old as Sunita. How old is Reena now ?
A. 6 years
B. 12 years
C. 14 years
D. 16 years

Answer : B. 12 years
Explanation :
Let Sunita’s present age = x years
Then Reena present age = 2x years
Three years ago
(2x-3) = 3(x-3)
2x – 3 = 3x – 9
Reena age = 2x = 2X6 = 12 year.
2. A group of 1200 persons consisting of captains and soldiers is travelling in a train. For every 15 soldiers there is one captain. The number of captains in the group is ?
A. 70
B. 75
C. 80
D. 85

Answer : B. 75
Explanation :
Generally we may commit mistake of dividing 1200/15.
But out of 16 persons there is one captain.
so, it will be 1200/16 = 75

3. First bunch of bananas has (1/4) again as many bananas as a second bunch. If the second bunch has 3 bananas less than the first bunch, then the number of bananas in the first bunch are
A. 9
B. 10
C. 12
D. 15

Answer : D. 15
Explanation :
Let the number of bananas in the second bunch be x.
Then, the number of bananas in the first bunch
= x + 1/4 x
= 5/4 x
So, 5/4 x – x = 3
=> 5x – 4x = 12
x = 12
Number of bananas in first bunch
= 5/4 X 12 = 15

4. 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. 24
D. 18

Answer : B. 16
Explanation :
Suppose boy got x sums right and 2x sums wrong,
then, x + 2x = 48
=> 3x = 48
=> x = 16

5. A father is now three times as old as his son. Five years back, he was four times as old as his son. The age of the son is :

A. 12
B. 15
C. 18
D. 20

Answer : B. 15
Explanation :
Let son’s age be x then father’s age is 3x
Five years ago, father’s age = 3x-5 and son’s age x-5
So, 3x-5 = 4(x-5)
=> 3x-5 = 4x-20
=> x = 15

10. If ‘MERCURY’ is written as ‘FGIECAB’ in a code, how can ‘CURE’ be written in that code?






1. B; Mr Anand and his wife = 2

           Prakash’s two married brothers = 4

           Two children = 2

           Total members = 8

2. D; Suppose the number of cows = x

           Therefore, the number of herdsmen = x

           According to the question,

           4 × 2x – 28 = x × 2 + x × 4

          ⇒ 8x – 28 = 2x + 4x  ⇔ 8x – 6x = 28

           ∴ x = 28/2 = 14

3. D

4. B; Total age of 19 boys = 19 × 21 = 399 years
