Question

A and B together can do a piece of work in 16 days and A alone can do it in 48 days.How long it will take for for B to complete the work ​

Answer 1

Step-by-step explanation:

A and B can do the work in 16 days. So in 1 day they can do 1/16 of the work in 1 day. Similarly, A alone will do 1/24 of the work in 1 day. Therefore, B alone can do 1/16 - 1/24 = 1/48 of the work in 1 day, which means that B alone can do the complete work in 48 days.
