Answer:
8 days
Step-by-step explanation:
A finishes the work in 12 days
B finishes the work in 4 days
L.C.M of 12 and 4 is 12
So, total work = 12
Efficiency of A = 12/12 = 1/day
Efficiency of B = 12/4 = 3/day
A and B wored together for 1 day = 1+3 =4
So, 12-4/12 = 8/12 is remaining work. A should complete it.
Therefore, Time taken by A is 8/12*12 = 8 days
