A's income is 25% more than B's. Find, how much percent B's income is less than A's ?

$\rule{400}{4}$

$\large{\underline{\red{\bf{Answer:-}}}}$

➠Let B's income be Rs. 100

We know A's income is more than B by 25%

➠Therefore, A's income = B's income + 25% of B's income

➠A's income = Rs. 100 + (25/100 * 100) = Rs. 100 + 25 = Rs. 125

$\rule{400}{4}$

A's income = Rs. 125

B's income = Rs. 100

$\rule{100}{2}$

➠B's income is less than A by Rs. 25

➠Percentage by which B's income is less

than A =$\sf{\dfrac{B's\:income\:less\:than\:A}{A's\:income}}$ * 100

ㅤㅤㅤㅤㅤㅤㅤㅤㅤㅤㅤㅤㅤㅤㅤㅤㅤ

$\implies$ (25/125) * 100 = 20%

$\rule{400}{4}$

Answer = $\boxed{\green{\huge{\bf{20\:percent}}}}$
