The monthly incomes of A and B are in the ratio 4 : 5, their expenses are in the ratio 5 : 6. If 'A' saves Rs.25 per month and 'B' saves Rs.50 per month, what are their respective incomes?
400,500
Let incomes be 4x and 5x.
Let expenditures be 5y and 6y.
So 4x−5y=255x−6y=50
So x=100
So the incomes of A and B are 400 and 500 respectively.
