Answer 1

$\tt {New \: salary \: after \: increase = ₹ \: 9936}$

$\tt {Let, x \: be \: the \: Initial \: salary}$

$Initial \: salary +15 \% \: of \: initial \: salary = New \: Salary$

$x+15 \%(x)=9936$

$x + \frac{15}{100}(x) = 9936$

$x + \frac{3}{20} (x) = 9936$

$x + \frac{3x}{20} = 9936$

$\huge \frac{(20x + 3x)}{20} = 9936$

$23x = 9936 \times 20$

$23x = 198720$

$\huge \: x = \frac{198720}{23}$

$\huge \: x = 8640$
