Question

The salary of a person was increased 15 %. If his salary now is rupees 9936 what is the initial salary​

Answer 1

Answer:

Rs 8640

Step-by-step explanation:

let initial salary be s

% increased = 15%

amount increased = s x 15% =s x (15/100) = s x 0.15

new salary = s + s x .15 = 9936

s + s x .15 = 9936

s(1 + .15) = 9936

s = 9936 / 1.15 = Rs 8640

Answer 2

$\huge\purple{\fbox{\fbox{\red{\mathcal{Bonjour}}}}}$

let the initial salary be X

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

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

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

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

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

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

$= > x = 432 \times 20$

$= > x = 8640(ans)$
