Question

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

Answer 1

Let B's income = Rs. 100
then A's income = 100+25
= Rs. 125
Now, difference of income of A and B
= Rs. (125-100) = Rs. 25
If A's income is Rs. 125, then B's income less than A = Rs. 25
If A's income is Rs. 1, then B's income less than A = Rs. $\frac{25}{125}$
If A's income is Rs. 100, then B's income less than A = Rs. $(\frac{25}{125}\times 100)$
= $\frac{1}{5}\times 100$ = Rs. 20
$\therefore$ B's income is less than A's income = 20%
