Answer 1

Answer:

A's monthly salary is 17500

Step-by-step explanation:

Let x be A's monthly salary.

80% of his salary is given by:

80/100 × x = 0.8x

He gives a quarter of this B which is:

1/4 × 0.8x = 0.2x

From this amount, B pays 20% towards rent. Meaning, he remains with (100% - 20%) = 80%

Now, 80% of what B gets is:

0.2x × 0.80 = 0.16x

This is equal to 2800, so we equate the two.

0.16x = 2800

x = 2800/0.16 = 17500

A's monthly salary is 17500
