A, B and C together earn Rs. 150 per day while A and C together earn Rs. 94 and B and C together earn Rs. 76. The daily earning of C is?

Rs. 75
Rs. 56
Rs. 34
Rs. 20

Correct Answer: Rs. 20

Explanation:

∵ B's daily earning = Rs. (150 - 94) = Rs. 56
⇒ A's daily earning = Rs. (150 - 76) = Rs. 74
∴ C's daily earning = Rs. [(150 - (56 + 74)] = Rs. 20
