Question 61

Ratio between the monthly income of A and B is 9 : 8 and the ratio between their expenditures is 8 : 7. If they save Rs. 500 each, find A’s monthly income.

Solution

Let monthly income of A = Rs. $$9x$$ and B = Rs. $$8x$$

Similarly, expenditure of A = Rs. $$8y$$ and expenditure of B = Rs. $$7y$$

=> Savings = $$9x-8y=500$$ -----------(i)

and $$8x-7y=500$$ --------------(ii)

Solving above equations, we get : $$x=500$$

$$\therefore$$ A's monthly income = $$9\times500=Rs.$$ $$4,500$$

=> Ans - (C)
