Question

The r=atio od the monthly incomes of a and b is 4:3. The ratio of their monthly expenditures is 5:4. If a saves one fourth of his mognthy incmoe, find te ratio of their monthly savings

Answer 1

Answer:

5:3

Step-by-step explanation:

let income of A be 4x then income of B be 3x and let expenditure of A be 5y then expenditure of B be 4y ..

Now, income - expenditure = saving

for A ,

4x - 5y = 1/4×4x

3x = 5y

y = 3x/5

saving of A = 4x - 5y

saving of B = 3x - 4y

ratio of saving of A and B = 4x -5y / 3x - 4y

putting the value of y from above equation which is y= 3x/5

and after solving after putting value of y , you will get ratio of saving as 5/3
