Best answer
Correct Answer - Option 1 : 48 years

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.
