Question

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 age?

Answer 1

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

According to the question,
$x+5=\frac{1}{3}\times 6x$
$\Rightarrow x+5=2x$
$\Rightarrow 2x=x+5$
$\Rightarrow 2x-x=5$
$\Rightarrow x=5years$
Hence, Shobo's present age = 5 years
And Shobo's mother's present age
$=6\times 5=30years$
