Detailed Solution
Download Solution PDFThe incomes of A and B are in the ratio 7: 5.
The expenditure of A and B are in the ratio 5: 3.
The saving of each is Rs. 10000
Income = Expenditure + Saving
Let the income of A and B be 7x and 5x
The expenditure of A=7x-10000
The expenditure of B=5x-10000
According to the question;
⇒ (7x-10000) /(5x-10000)=(5/3)
⇒ 21x-30000=25x-50000
⇒ 4x=20000 ⇒ x = 5000
The income of A=7×5000= Rs. 35000
The income of B=5×5000= Rs. 25000
sum of income = 35000+25000 = Rs. 60000
