Question

A man is $7$ times as old as his son. If he is $56$ years, find the age of his son.

Answer 1

Given: A man is $7$ times as old as his son and now he is $56$ years.

Let the age of his son be $\mathrm{x}$ years. so, man age will be $7\mathrm{x}$.

$$\begin{gathered} \Rightarrow 7\mathrm{x}=56 \\ \Rightarrow \mathrm{x}=\frac{56}{7} \\ \Rightarrow \mathrm{x}=\frac{{\displaystyle \stackrel{8}{\cancel{56}}}}{\cancel{7}} \end{gathered}$$

Hence, the age of his son is $8$ years.
