### Question

After getting a rise of 15%, a man’s new monthly salary is N345. How much per month did he earn before the increase?

A) ₦330

B) ₦396.75

C) ₦300

D) ₦293.25

E) ₦360

### Explanation:

Let $$x$$ represent his monthly salary before the increase of 15%.
$$x = 345$$
$$115100x = 345$$
$$115x = 34500$$
$$x = ₦300$$

## Discussion (2)

• Let $$x$$ represent his monthly salary before the increase of 15%.
$$x = 345$$
$$115100x = 345$$
$$115x = 34500$$
$$x = ₦300$$

The correct answer is D not C. If you find 15% of N 345, you get N 51.75 then you subtract it from the new salary which is N 345, so you get N 293.25
