Explanation:

Total amount earned by A ,B, and C in 6 days =Rs 480
The amount earned by them in 1 day = 480/6 = Rs 80
Amount of money earned is proportional to the amount of work done.
Let work done by A ,B and C be 4x, 5x and 7x.
∴ Total work done by A,B and C together= 16x
Work done by B = 5x
Daily income of B = 5x /16x * 80 = Rs. 25
