Answer 1

Answer: 4025,575

Step-by-step explanation:

1) According to the question, ratio if respective income be 3:7:4.

Let the income and expenditure of A, B and C be is 3x,7x and 4x and 4y,3y and 5y respectively.

We know, the income of A is 2400.

=> 3x =2400

=> x = 800

Also,

2) A saves 300 .

=> 3x-4y=300

=>3*800-4y=300

=>y=525

3) Now, savings of B :

7x-3y = 7*800-3*525=4025

Savings of C

,4x-5y = 4*800-5*525=575
