A, B and C contract a work for Rs. 550. Together A and B are supposed to do 7/11 of the work. The share of C should be?

Rs. 1831/3
Rs. 200
Rs. 300
Rs. 400

Correct Answer: Rs. 200

Explanation:

Work to be done by C = (1 - 7/11) = 4/11
∴ (A + B) : C = 7/11 : 4/11 = 7 : 4
∴ C's share = Rs. 550 x (4/11) = Rs. 200
