Question

A sons current age is half the present age of his father 10 years ago his father was was thrice as old as his son what is there current age assume the father’s age as x

Answer 1

Step-by-step explanation:

Given that,

The present age of son is half the present age of his father.

Let the present age of the father be 2x.

Therefore present age of the son = 2x/2 = x years

ATQ,

10 years ago, father's age was thrice as old as his son.

➡ 3(x - 10) = 2x - 10

➡ 3x - 30 = 2x - 10

➡ 3x - 2x = -10 + 30

➡ x = 20

Hence their present ages are :-

Father's present age = 2x = 40 years

His son's present age = x = 20 years
