A father is nine times as old as his son and the mother is eight times as old as the son. The sum of the father's and the mother's age is 51 years. What is the age of the son ?
3 year
Let x be age of the Son Since the father is nine times as old as son and mother is eight times as old as son, so we can write this as 9x and 8x Further it is given that the sum of father's and mother's age is 51 years, so we can write this as: 9x + 8x = 51 Now solving for x, we get 17x = 51 x=3, hence correct option is D.
