Question
The income of P is 4/5th of the income of Q
and income of R is 60% more than the income of Q. Income of Q is Rs.20000 and expenditure of P is 35% of the expenditure of R. If R saves 40% of his income, then find the savings of P.Solution
Income of Q = Rs.20000 Income of P = 4/5 × 20000 = Rs.16000 Income of R = (160/100) × 20000 = Rs.32000 Savings of R = 32000 × (40/100) = Rs.12800 Expenditure of R = 32000 - 12800 = Rs.19200 Expenditure of P = (35/100) × 19200 = Rs.6720 Savings of P = 16000 - 6720 = Rs.9280
