I guess this is the right solution

Answer 2

Answer:

The 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.

$3x=2400$

$x=800$

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.

$4y=2100$

$x=525$

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.
