A father's age is one more than 5 times of his son's age. After 3 years, the father's age would be 2 less than four times the son's age. Find the present age of the father.

Options

A. 30 yr
B. 40 yr
C. 31 yr
D. 29 yr

Answer

C

Explanation

Let present age of son = `x yr`
Then, present age of father = `(5x + 1) yr `
According to the question,
`= 4(x + 3) - 2 = (5x + 1) + 3`
`implies 12 -2- 4 = 5x - 4x`
`implies x = 6 yr `
Present age of father = `5x + 1`
`= 5x 6+ 1 = 31 yr `
