Answer 2

Answer:

The income of B is 50% more than C.

Step-by-step explanation:

It is given that income of A is 20% less than B and income of A is 20% more than C.

Let income of B be x.

Income of A is 20% less than B.

$A=x-\frac{20}{100}x=x-0.2x=0.8x$

The income of A is 0.8x.

Let income of C be 100.

Income of A is 20% more than C.

$A=100+\frac{20}{100}(100)=100+20=120$

If income of C is 100, then the income A is 120.

$0.8x=120$

$x=150$

The value of x is 150. It means if income of C is 100, then income of B is 150.

$P=\frac{B-C}{C}\times 100$

$P=\frac{150-100}{100}\times 100=50$

Therefore, the income of B is 50% more than C.
