The income of P is 2/5th of the income of Q
and income of R is 60% more than the income of Q. Income of Q is Rs.30000 and expenditure of P is 20% of the expenditure of R. If R saves 25% of his income, then find the savings of P.Solution
Income of Q = Rs.30000 Income of P = 2/5 × 30000 = Rs.12000 Income of R = (160/100) × 30000 = Rs.48000 Savings of R = 48000 × (25/100) = Rs.12000 Expenditure of R = 48000 - 12000 = Rs.36000 Expenditure of P = (20/100) × 36000 = Rs.7200 Savings of P = 12000 - 7200 = Rs.4800
