The monthly incomes of Abhinav and Rekhaare in the ratio 6:5 and their monthly expenditures are in the ratio 9:8. If the income of
Abhinavis twice the expenditure of Rekha, then the ratio of savings ofAbhinav and Rekha is:

lets say the income of A =6x and income of R = 5x and expenditure of A= 9y and R =8y
now given 6x =2(8y)
x/y = 8/3
so income of A =480 and expenditure =270 ,hence saving = 210 similarly income of R = 240 and expenditure = 240, hence saving = 160
ratio of saving 21:16
