Answer:
the answer is 18/5 days
Step-by-step explanation:
Lcm of 6 and 4 is 12 so let total work be 12 units
Work done by A in one day = 12/6 = 2units
Work done by B in one day = 12/4 = 3 units
A working for 2 days will do 2*2 units = 4 units of total work
Remaining work = 12–4 = 8 units
Since B has joined A after this both will together finish remaining work = 8/2+3 = 8/5 days
Total time taken = A's 2 day work + 8/5 days
= 18/5 days
