Question

The salary of an employee was increased by 10%. If the present salary is Rs.9900. Find his salary before increment.​

Answer 1

Answer:

Let x be the original salary

x + 10x/100 = 9900

x + x/10 = 9900

11x/10 = 9900

11x = 9900 × 10

x = 99000 / 11

= 9000

Answer 2

Answer:

Rs 9000

Step-by-step explanation:

Salary before increment = 100%

Salary after increment = 110%

$110\% - - - - - 9900 \\ 100\% - - - - - - x \\ x = \frac{100 \times 9900}{110} = 9000$
