Question

the salary of a person was increased by 15% if his salary now is rupees 9936 what was his initial salary​

Answer 1

Answer:

Step-by-step explanation:

Given,

% increase in salary = 15% = 3/20

New salary = 9936.

Assume the initial salary as 'x'.

So, x*(1 +(3/20) )= 9936

Solve the above eq , we get the initial value 'x' = 8640.

Answer 2

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

let the initial salary be X

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

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

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

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

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

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

$= > x = 432 \times 20$

$= > x = 8640(ans)$
