The monthly incomes of two friends Kiran and Mahesh, are in the ratio 5 : 7 respectively and each of them saves ₹78,000 every month. If the ratio of their monthly expenditure is 1 : 3, find the monthly income of Kiran (in ₹).
97,500
Let the monthly incomes of Kiran and Mahesh be ₹5x and ₹7x respectively. Their savings are ₹78,000 each.
The total income minus expenditure equals savings, so:
Income of Kiran - Expenditure of Kiran = 78,000
5x - Expenditure of Kiran = 78,000
The ratio of their expenditures is 1:3, so Expenditure of Kiran = ₹26,000. Therefore:
5x - 26,000 = 78,000 => 5x = 1,04,000 => x = 20,800
Thus, the monthly income of Kiran is 5x = 5 * 20,800 = ₹1,04,000.
