P's income is 150 percent of Q's income and P's expenditure is 60 percent of Q's expenditure. If Q saves 20 percent of his income, then how much percentage does P save of his own income? |
68 percent 60 percent 72 percent 75 percent |
68 percent |
P's income is 150 percent of Q's income Let Q's income = 100 P's income = 150% of 100 = 150 Q saves 20% of his income . Q's saving = 20% of 100 = 20 Expenditure = 100 - 20 = 80 P's expenditure is 60 percent of Q's expenditure P's expenditure = 60% of 80 = \(\frac{3}{5}\) × 80 = 48 Saving of P = 150 - 48 = 102 Required percentage = \(\frac{102}{150}\) × 100 = 68% |
