Correct option is C

Given:

Srinivas’s wife is younger to him by 4 years

Average of Srinivas and his wife’s age after 5 years = 33years

Formula Used:

Ratio and Proportions

Solution:

Let the age of Srinivas be x

Then age of Srinivas’s wife is x -4

Age of Srinivas after 5 years = x + 5

Srinivas’s wife’s age after 5 years = (x - 4) +5 = x + 1

Total age of Srinivas and his wife after  5 years = (x+5) + (x+1) =2x+6

If average of both ages after 5 years is 33 years

Then total age will be = 33$$\times$$​ 2 = 66

So, 2x+6 = 66

x = 30years

Present age of the girl = x - 4 = 26years
