Given the age of Sunil is 48
Which is equal to 5x-7
i.e.
5x=48+7=55
x=55/5=11

Answer 2

$\mathbb{GIVEN \: :}$
Sunil is 48 years old.
Sunil is 7 years less than 5 times of his daughter's age.

Let,
His daughter's age be x years.

According to the question,
Sunili is 7 years less than 5 times of his daughter's age.

=> 5x - 7 = 48

=> 5x = 48 + 7

=> 5x = 55

=> x = $\frac{55}{5}$

=> x = 11

Hence,
$\bf{Sunil's \: daughter\: age\: is \:11 \:years\: old. }$
