• A. same as A's
• B. 20% less than A's
• C. $16\frac{2}{3}$ % less than A's
• D. 15% less than A's

Answer 1

The correct option is C $16\frac{2}{3}$ % less than A's

Let B’s income $=x$

A’s income is $20$% more than B.

$=x+\frac{20}{100}x$

$=\frac{6}{5}x$

B’s income in terms of A

$=\frac{\frac{6}{5}x-x}{\frac{6}{5}x}\times 100$

$=\frac{1}{6}\times 100$

$=16\frac{2}{3}$% less than A.

Hence, this is the answer.
