Deepak was given an increment of 12% on his salary. His new salary is ₹76,720. What was his salary before the increment?

Correct option is C

Given:

Deepak was given an increment of 12% on his salary.

His new salary after the increment is ₹76,720.

Solution:
Let Deepak's salary before the increment be x.

After the 12% increment, his new salary is:

New salary = $$x + \frac{12}{100} \times x = x \left(1 + \frac{12}{100}\right) = x \times 1.12$$​

We are given that his new salary is ₹76,720:

x × 1.12 = 76,720

x =$$\frac{76,720}{1.12} =$$​68,500.

Deepak's salary before the increment was ₹68,500.
