IBPS SO Prelims Exam Model Paper 7

GIVEN:
average age of all three 4 years ago = 32 years
average age of Ram and Ajay 2 yeas ago = 28 years
FORMULA USED:
sum of present age = number of people × (average age before + number of years)
EXPLANATION:
Sum of the present ages of all three = 3 × (32 + 4)
= 108 years
Sum of present age of Ram and Ajay = 2 × (28 + 2)
= 60 years
Sumit's present age = 108 - 60 = 48 years
∴ The present age of Sumit is 48 years.
