Question

13. A and B together can do a piece of work in 12 days, B alone can do it in 20 days. how many days can A alone finish the work.​

Answer 1

Answer:

20 days

A’s 1 day’s work $latex = \frac{1}{12}-\frac{1}{30} = \frac{5-2}{60} = \frac{3}{60} = \frac{1}{20}&s=1$

So, A alone will complete the work in 20 days.

Hence
