1. 53 years
2. 43 years
3. 73 years
4. 63 years

Answer 1

Correct Answer - Option 4 : 63 years

Given

Sum of ages of X, Y and Z three years ago was 150

and ratio of their age was 6 : 4 : 5

Calculation

6x + 4x + 5x = 150

15x = 150

x = 10

X's age three years ago was 60 years (i.e. 6 × 10)

Present age of X is 63 years (i.e.60 + 3)
