Question

The income of A and B are in the ratio 3:2and their expendable in the ratio 5:3. if each savesRs1000 then A's income is__________________ ?

Answer 1

Let x be the common factor for income
Then we have As income=3x and B's income=2x
A spends 3x-1000 and B spends 2x-1000
ATQ we have (3x-1000)/(2x-1000)=5/3
                ⇒  9x-3000=10x-5000
                ⇒  x=2000
A's income=3x=3*2000=Rs6000
