Answer:
Time taken by A and B =10 days and Time taken by C =50 days
Total work=50 units
Efficiency of A and B = 5
Efficiency of C =1
A=B+C is given
A+B=5 => B+C+B=5 => 2B+C=5
2B+1=5 =>2B=4
B=2 is the efficiency
Time taken by B= work /efficiency of B =>50/2 =25
Therfore, B can complete the work in 25days
