Answer 2

Answer:-

The initial salary of the person is Rs. 8640

Step-by-step explanation:-

To Find:-

• The initial salary ................(?)

Given:-

• Percentage of salary increased is 15%
• New salary is Rs. 9936

Solution:-

Let the initial salary be x

Now,

$\sf{Initial \: salary + 15\% \: of \: initial \: salary} \\ = \bf{ New \: salary}$

Therefore,

By putting the values,

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

$\implies \: x + \dfrac{15}{100} \times x = 9936$

$\implies \: x + \dfrac{3}{20} \times x = 9936$

$\implies \: x + \dfrac{3x}{20} = 9936$

$\implies \: \dfrac{20x + 3x}{20} = 9936$

$\implies \: 23x = 9936 \times 20$

$\implies \: 23x = 198720$

$\implies \: x = \dfrac{198720}{23}$

$\implies \: x = 8640$

Therefore, the initial salary is Rs. 8640.

Required Answer:-

The initial salary of the person is Rs. 8640.
