After 10 years the age of the son is,
(A) 17 years
(B) 45 years
(C) 18 years (D) 28 years​

Answer 1

Answer:

option d is a correct answer

Answer 2

Age of father : age of son = 5:2
Age of father + age of son = 63 years

Let the constant ratios be x
5x + 2x = 63 years
7x = 63 years
x = 63/7
x = 9

Age of father = 5x = 5 * 9 = 45 years
Age of son = 2x = 2 * 9 = 18 years

Age of son after 10 years = 18 + 10 = 28 years

Therefore, the age of the son after 10 years is 28
