Question

The salary of a person was increased by 15%. If his salary now is ₹9936, what was the initial salary

Answer 1

Let his initial salary be Rs. x.
A.t.q,
x+x×15/100=9936
x+3x/20=9936
(20x+3x)/20=9936
23x/20=9936
x = (9936 ×20)/23
x = 8640

Answer 2

let the initial salary be X

$x + 15\% \: of \: x = 9936$

$= > \frac{x}{1} \times \frac{100}{100} + \frac{15}{100} \times x = 9936$

$= > \frac{100x + 15x}{100} = 9936$

$= > \frac{115x}{100} = 9936$

$= > x = 9936 \times \frac{100}{115}$

$= > x = 9936 \times \frac{20}{23}$

$= > x = 432 \times 20$

$= > x = 8640(ans)$
