5.Shobo’s mother’s present age is six times Shobo’s present age. Shobo’s age five years from now will be one third of his mother’s present age. What are their present ages?

Let Shobo’s present age be x years.
And Shobo’s mother’s age = 6x years.

After 5 years Shobo’s age=(x + 5) years.

As per the condition given, we have

x + 5 =\( \frac { 1 }{ 3 }\) × 6x

\(\Rightarrow\) x + 5 = 2x

\(\Rightarrow\) 5 = 2x – x (Transposing x to RHS)

\(\Rightarrow\) 5 = x

Hence, Shobo’s present age = 5 years

and Shobo’s mother’s present age 6x = 6 × 5 = 30 years.
