Question

1. A's income is 60% more than of B. By what
percent B's income less than A's​

Answer 1

Answer:

37.5%

Step-by-step explanation:

A's income is 60% more than of B

This sentence means,

$\mathrm {A = \frac{60 B}{100}+B } \\\\=> \mathrm{A = \frac{160B}{100} }$

Now,

$\mathrm {B = \frac{100A}{160} } \\\\=> \mathrm {B = \frac{5A}{8} }\\\\=> \mathrm{B = A - \frac{3A}{8} } \\\\=> \mathrm {B = A - \frac{3 * 12.5 A}{8*12.5} } \\\\=> \mathrm{B = A - \frac{37.5A}{100} } \\\\=> \mathrm {B = A - 37.5\%A}$

B's income 37.5% less than A's​
