A is 50% as efficient as B. C does half of the work done by A and B together. If C alone does the work in 20 days, then A, B and C together can do the work in

A is 50% as efficient as B.C does half of the work done by A and B together. If C alone does the work in 40 days, then A, B and C together can do the work in: 13 1/3d a y s b. 15 d a y s c. 20 d a y s d. 30 days

A and B together can do a work in 10 days. B and C together can do the same work in 6 days. A and C together can do the work in 12 days. Then A, B and C together can do the work in

A does half as much work as B and C does half as much work as A and B together. If C alone can finish the work in 40 days, then all together will finish the work in?

A does half as much work as B, and C does half as much work as A and B together. If C alone can finish the work in 40 days, then all together will finish the work in (B) 15 days (A) 13(1/3) days (D) 30 days (C) 20 days

A and B together can do a piece of work in 20 days, while B and C together can do the same work in 15 days. If A ,B and C together can finish this work in 10 days, then find the number of days in which B alone can finish the work.

A and B together can do a piece of work in 20 days, while B and C together can do the same work in 15 days. If A ,B and C together can finish this work in 10 days, then find the number of days in which B alone can finish the work.

A takes as much time as B and C together to complete a work. While A and B together can do this piece of work in 10 days. C alone can do this piece of work in 50 days. In how many days will this work be completed by B alone?
