Salil’s salary was first reduced by 15% and subsequently raised by 10%. What percentage was his final salary lower compared to his initial salary?

Correct option is C

Given:

Salil’s salary is reduced by 15% and then raised by 10%.

Formula Used:

Percentage change = $$x + y + \frac{xy}{100}$$​​

Solution:

Substitute x = -15 and y = 10 into the formula:

Percentage change = $$-15 + 10 + \frac{(-15) \times 10}{100}$$​​

​$$= -15 + 10 - \frac{150}{100}$$​​

= -15 + 10 - 1.5

= -6.5

Thus, the salary decreases by 6.5%
