Question
The income of P is 4/7th of the income of Q
and income of R is 40% more than the income of Q. Income of Q is Rs.21000 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.21000 Income of P = 4/7 × 21000 = Rs.12000 Income of R = (140/100) × 21000 = Rs.29400 Savings of R = 29400 × (40/100) = Rs.11760 Expenditure of R = 29400 - 11760 = Rs.17640 Expenditure of P = (35/100) × 17640 = Rs.6174 Savings of P = 12000 - 6174 = Rs.5826
