Best answer
Correct Answer - Option 3 : 45, 95

Let the age of X be x years.

⇒ Age of her grandfather = x + 50 years

A.T.Q

After 6 years, the sum of their ages is 152

⇒ x + 6 + x + 50 + 6 = 152

⇒ 2x + 62 = 152

⇒ 2x = 90

x = 45 

Thus age of her grandfather = 45 + 50 = 95 years.

Hence, the correct answer is "Option 3".
