A, B and C contract to do a work for Rs. 4200. A can do the work in 6 days, B in 10 days and C in 12 days. If they work together to do the work, what is the share of C (in Rs.)?
A1000
B2000
C1500
D1200
Answer:
A. 1000
Read Explanation:
Total work = LCM of 6, 10, 12 = 60
Efficiency of A = 60 /6 = 10
Efficiency of B = 60/10 = 6
Efficiency of C = 60 /12 = 5
Efficiency of all together = 10 + 6 + 5 = 21
Share of C = (4200×5)/ 21 = Rs. 1000
