Question

Sunil is $48$ years old. He is $7$ years less than $5$ times his daughter's age. What is his daughter's age

Answer 1

Let $x$ be the age of Sunil's daughter.

According to the question

$48=5x-7$

$\Rightarrow 5x=48+7$

$\Rightarrow x=\frac{55}{5}=11$

Hence Sunil's daughter is $11$ years old.
