Detailed Solution
Download Solution PDFGiven:
Ratio of monthly incomes of Vipul and Vijay = 5 : 7
Monthly saving of each = ₹81000
Ratio of their monthly expenditure = 2 : 4
Formula Used:
Income = Expenditure + Saving
Calculation:
Let the monthly income of Vipul be 5x and the monthly income of Vijay be 7x.
Expenditure of Vipul = Income of Vipul - Saving of Vipul = 5x - 81000
Expenditure of Vijay = Income of Vijay - Saving of Vijay = 7x - 81000
Ratio of their monthly expenditure = (5x - 81000) : (7x - 81000) = 2 : 4
⇒ (5x - 81000) / (7x - 81000) = 2 / 4
⇒ (5x - 81000) / (7x - 81000) = 1 / 2
⇒ 2 × (5x - 81000) = 1 × (7x - 81000)
⇒ 10x - 162000 = 7x - 81000
⇒ 10x - 7x = 162000 - 81000
⇒ 3x = 81000
⇒ x = 81000 / 3
⇒ x = 27000
Monthly income of Vipul = 5x = 5 × 27000 = ₹135000
The monthly income of Vipul is ₹135000.
