Correct Answer - Option 2 : 150%
Given:
Income of A = 60% less than B's income
Concept used:
⇒ % more = {(grater value - lesser value) × 100}/lesser value
Calculations:
Let, the income of B = 100
⇒ Income of A = 100 × 40%
⇒ Income of A = 40
⇒ % more = (100 - 40) × 100/40
⇒ % more = (60 × 100)/40
⇒ % more = 150%
∴ B's income is 150% percentage more than that of A's income.
