Let the present age of Shobo's be x years. Then, Shobo's mother's present age = 6x year
Five years from now
Shobo's age = (x + 5) years
According to the question,
{tex}x + 5 = \frac{1}{3}(6x){/tex}
∴ x + 5 = 2x
∴ 5 = 2x – x . . . . [Transposing x to R.H.S.]
∴ 5 = x
∴ x = 5
∴ 6x = 6 × 5 = 30 hence, their present ages are 5 years and 30 years.
Verification
30 = 5 × 6
5 + 5 = 10
{tex}10 = \frac{1}{3}(30){/tex} hence, the result is verified.
