Best answer
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
