Question

A number is increased by $12$ and the new number obtained is multiplied by $5$.If the resulting number is $95$, find the original number.

Answer 1

Let the original number$=x$

$\Rightarrow (x+12)\times 5=95$

$\Rightarrow 5x+60=95$

$\Rightarrow 5x=95-60=35$

$\Rightarrow x=\frac{35}{5}=7$

$\therefore$ The original number$=7$
