Question

The salary of a clerk was inscribed by $7\%$. If his present salary is $Rs1519.40$, what it was before the increment?

Answer 1

Let the previous salary be $x$

Increased salary$=x+(x+7\%)=x+\frac{7x}{100}=\frac{107x}{100}$

Now, $\frac{107x}{100}=$Rs $1519.40$

$\Rightarrow x=\frac{1519.40\times 100}{107}=$Rs$1,420‬$

His previous salary was Rs$1,420‬$

$\therefore$, Increment$=$Rs $1519.40-$Rs$1420.00=‬$Rs.$99.4‬0$
