Question
A’s income is 25% more than B’s. Find, B’s income is how much percent less than A’s.
Solution
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 Rs1, the B's income less than A
= Rs.`(25)/(125)`
If A's income is rs.100, then B's income less than A
= Rs. `(25/125 xx 100)`
= `(1)/(5) xx 100`
= Rs.20
∴ B's income is less than A's income = 20%
