Rs. 575

Ratio of incomes A : B : C = 3 : 7 : 4
As A's incomes is Rs. 2400, so incomes of B=2400*7/3=Rs. 5600 and C=2400*4/3=Rs. 3200
Let their expenditures be 4x, 3x and 5x
Given saving of A=2400 - 4x = 300 => 4x=2100 or x=525
So the expenditure of B=3x=3*525=Rs. 1575 and C=5x=5*525=Rs. 2625
Hence saving of C=3200 - 2625 =Rs. 575
