Question

The ratio of the incomes of A and B is 3 : 5, whereas the ratio of their expenditure is 4 : 7

respectivley . If A and B save Rs. 16,000 and 26,000 respectivley then what is the difference

between their expenditures?​

Answer 1

Answer:

Rs 60000

Step-by-step explanation:

incomes of A&B = 3x,5x

Their expr:=4 y, 7y

.Savings of A. 3x-4y=16ooo... (1)

savings of B. 5x-7y=26 ooo... (2)

(i) x5-> 15x-20y=80000

(2) x3-> 15x-2ly=78000

deduct..........y =2000

puty=2ooo in eqn (i)

3x-4y=16000

3x-8000 = 16000

3x = 24000

x = 8000

x=Rs8000

y = Rs 2000

Ratio of expenditures of A&B = 4y, 7y

4 y=4x2ooo=Rs8000 (A)

7y=7x2000 = Rs 14000 (B)

difference b/w exprs: of A&B = 14000-8000

= Rs6000
