# How Much Does C Get? If

A and B are assigned a work for Rs.37.50. A can do it in 20 days, while B in 30 days, If they complete the work in 8 days with the help of C, then how much does C get?

- Rs.12.5
- Rs.13
- Rs.14
- Rs.15

**Answer: (a) 12.5
Explanation:-
**A can do a work = 20 days

A can do work in a day = 1/20

B can do work = 30 days

B can do work in a day = 1/30

A and B together can do work in a day = 1/20 + 1/30

= 5/60 = 1/12

A, B and C together can do work = 8 days

C can do it = 1/8 – 1/12 = 1/24

The ratio A, B and C = 20: 30: 24 = 10: 15: 12

C gets = 12 x 37.50/37 = Rs.12.16
