Discussion

Explanation:

A can complete the work in 16 days.

Since B completes only half the work in a day as A, it means B will take twice the time than A to complete a certain work.

∴ If A can complete a certain task in 16 days, B will take 32 days to complete the same task.

∴ (A + B)’s work in 1 day = 1/16 + 1/32 = 3/32.

Hence, time taken by A and B together to complete the work = 32/3 days

Hence, option (c).
