Question

The income ratio of A B C is 3:7:4 and their

expenditure ratio is 4:3:5. A saves Rs300 out of his

total income Rs 2400 then find difference

between the savings of B and C?​

Answer 1

Answer:

he saving of b is 4025 and the saving of c is 575.

Step-by-step explanation:

The ratio of income of a,b, c is 3:7:4 respectively. Let the income be 3x, 7x, 4x respectively.

The ratio of expenses of a,b, c is 4:3:5 respectively. Let the expenditure be 4y, 3y, 5y respectively.

It is given that the income of a is 2400.

3$x$ = 2400

$x$ = 2400/3 = 800

The value of x is 800, therefore the income of a, b, c is 2400,5600, 3200 respectively.

expenditure = income - saving

expenditure = 2400 - 300 = 2100

The expenses of a is 2100.

4$y$  = 2100

$y$ = 2100/4 = 525

The value of y is 525, therefore the expenditure of a, b, c is 2100,1575, 2625 respectively.

Saving of b is

5600 - 1575 = 4025

Saving of c is

3200 - 2625 = 575

Therefore the saving of b is 4025 and the saving of c is 575.
