The monthly incomes of two friends Chetan and Vipul, are in the ratio 5 : 7 respectively and each of them saves ₹96000 every month. If the ratio of their monthly expenditure is 2 : 4, find the monthly income of Chetan(in ₹).
Given:
Income ratio (Chetan : Vipul) = 5 : 7
Expenditure ratio = 2 : 4
Each saves = ₹96,000
Formula Used:
Income = Expenditure + Savings
Solution:
Let incomes = 5x, 7x and expenditures = 2y, 4y.
For Chetan: 5x − 2y = 96,000
For Vipul: 7x − 4y = 96,000
Subtract
2x − 2y = 0
x = y.
Then 5x − 2x = 96,000
3x = 96,000
x = 32,000
Chetan’s income = 5x = 5 × 32,000 = ₹1,60,000
