Q:

A) 31 years | B) 37 years |

C) 46 years | D) 29 years |

Answer: A) 31 years

Explanation:

Explanation:

Let the present age of Pinky be x years

Then the age of Mary is x - 12 years

After 3 years,

Ratio of $\frac{Mary}{Pinky}=\frac{\mathbf{x}\mathbf{}\mathbf{-}\mathbf{}\mathbf{9}}{\mathbf{x}\mathbf{}\mathbf{+}\mathbf{}\mathbf{3}}\mathbf{}\mathbf{=}\mathbf{}\frac{\mathbf{5}}{\mathbf{8}}$

8x - 72 = 5x +15

=> 3x = 87

=> x = 29

=> Age of Pinky = 29 years

=> Age of Mary = 29 - 12 = 17 years

Present age of Sam = 29 + 17 = 46

Before 15 years Sam age = 46 - 15 = 31 years.
