Question
The monthly income of 'C' is Rs. 30,000 whereas the
monthly income of 'D' is 50% more than that of 'C'. Find the difference between the savings of 'C' and 'D' if 'C' and 'D' spend 30% and 50% of their respective incomes.Solution
ATQ, Monthly income of 'D' = 150% of 30,000 = (1.5) X 30,000 = Rs. 45,000 Savings of 'C' = (100 - 30) % of 30,000 = (0.7) X 30,000 = Rs. 21,000 Savings of 'D' = (100 - 50) % of 45,000 = (0.5) X 45,000 = Rs. 22,500 So, required difference = 22,500 - 21,000 = Rs.1,500
