Correct Answer - Option 2 : Rs. 250
Solution:
Calculations:
Total amount earned by A, B, and C in 6 days = Rs. 4800
The amount earned by them in 1 day = 4800/6
⇒ Rs. 800
The 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 × 800
⇒ Rs. 250
