Answer 1

let the salary is x before increase۔ATQ

$x + 15\% = 9936 \\ x + \frac{15x} {100} = 9936 \\ \frac{100x + 15x}{100} = 9936 \\ \frac{115x}{100} = 9936 \\ x = 9936 \times \frac{100}{115} \\ x = 432\times \frac{100}{5} \\ x = 432 \times 20 \\ x = 8640$

let the initial salary be X

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

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

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

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

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

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

$= > x = 432 \times 20$

$= > x = 8640(ans)$
