If 'A' is 7 times as efficient as 'B', 'B' takes 32 days to complete the task, then find the number of days required to finish the whole work by 'A' and 'B' working together.
24 men can do work in 16 days, while 32 women do the same work in 24 days. If 16 men and 16 women started the work, then after 12 days how many more men needed to finish the remaining work in 2 days?
