A alone can finish a work in 10 days and B alone can do it in 15 days. If they work together and finish it, then out of a total wages of Rs. 75, A will get?
Correct Answer: Rs. 45
Explanation:
Since a alone can finish a work in 10 days and B alone can do it in 15 days. So if they work together then the ration of work done by A and B is = (1/10) : (1/15). ∴ The wages A will get = (1/10)[(1/10) + (1/15)] x 75
= Rs. 45
