Question

if As income be 25% more that of Bs then find the percentage of difference of Bs income from As income​

Answer 1

Given :

A's income = 25 % more than B's.

According to the question :

Let B's income be = Rs. 100.

A's income = 25 % + B's

=> 100 + 25 % of 100

=> 100 + 25 / 100 × 100

=> 100 + 25

=> $\sf\large\underline\blue{Rs.125}$

A's income = $\sf\large\underline\red{Rs.125}$

B's income = $\sf\large\underline\red{Rs. 100}$

Percentage of difference :

B - A = 125 - 100 => $\sf\large\underline\blue{Rs.25}$

Let ' x ' be the percentage.

=> x / 100 × 125 = 25

=> x = 25 × 100 / 125

=> x = 100 / 5

=> $\sf\large\underline\blue{x\:=\:20}$

Percentage of difference =

20 %
