Let initial income of B = 100 Then, Initial Income of A = 150 Total initial income = 100 + 150 = 250 |
Income of A is increased by 40%: New income of A = 150 × 1.4 = 210 Income of B is increased by 90%: New income of B = 100 × 1.9 = 190 Total new income = 210 + 190 = 400 Hence, Percentage increase = [(400 – 250)/250] × 100 = 1500/25 = 60% |
