The ratio of expenditure and savings of a person is 5 : 3. If the income increases by 20% and the expenditure increases by 16\(\frac{2}{3}\)%, then the person’s savings increase by: |
63.96% 55% 35% 63.5% |
63.5% |
Ratio of expenditure and savings = 3 : 5 Income = 8R Increased Income = \(\frac{6}{5}\) x 8R = \(\frac{48R}{5}\) Increased expenditure = \(\frac{7}{6}\) x 3R = \(\frac{7R}{2}\) Change in savings = \(\frac{48R}{5}\) - \(\frac{7R}{2}\) = \(\frac{61R}{10}\) Percentage change = \(\frac{\frac{61R}{10}}{\frac{48R}{5}}\) x 100 = 63.5% |
