Two persons A and B can complete a work in 10 and 15 days respectively, working separately. If they work together and receive Rs.300 as payment, what is A's share?
ARs.120
BRs.150
CRs.180
DRs.200
Answer & Solution
Correct answer: C. Rs.180
Their work-rate ratio is $1/10:1/15=3:2$. Wages are divided in the same ratio because both work for the same duration. So A gets $\frac{3}{3+2}\times 300=\frac{3}{5}\times 300=180$. Hence A's share is Rs.180.
