Question 62
Incomes of A and B are in the ratio 5 : 3 and their expenditures are in the ratio 9 : 5. If income of A is twice the expenditure of B, then what is the ratio of savings of A and B?
Solution
Let income of A be 5x
so income of B will be 3x
Now let expenditure of A be 9y
so expenditure of B will be 5y
Now as per given condition
we get 5x=10y
or x = 2y
so 3x will be 6y
Now saving of A = 5x-9y =y (1)
saving of B will be 3x-5y = y (2)
Therefore ratio of savings = 1:1
