Question

The salary of a person was increased by 15%.if his salary now is 9936 what was his initial salary

Answer 1

salary will be = 9936-15/100
i.e. 9936-0.15
=9935.85

Answer 2

Step-by-step explanation:

let the initial salary be x

$x + 15\% = 9936$

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

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

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

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

$x = \frac{100}{15} \times 9936$

$\frac{100}{115} will \: be \: cancelled \: \frac{20}{23}$

$\frac{20 \times 9936}{23}$

23 will be cancelled 23 once and 9936will be cancelled and the result is 432

$x = 20 \times 432$

$x = 8640$
