• A. 25
• B. 30
• C. 33 1/3
• D. 66 2/3

Answer 1

Answer:

C. 33 1/3

Solution:

A's Income is 25% less than that of B's Income.

$A=\frac{75}{100}B$

$\frac{A}{B}=\frac{3}{4}$

$A : B= 3:4$

Percentage of B's Income more than that of A's income $=\frac{4-3}{3}\times{100}$

$=\frac{1}{3}\times{100}=33\frac{1}{3}$
