Question

A can do a piece of work in 12days. B can do the same work in 26days. They work together for 3days and then A goes away. In how many days will B finish the work​

Answer 1

A can do a piece of work in one day = 1/12

we can do the same work in one day= 1/26

(1/12+1/26) days

(13+6/156) days =(19/156) days

a work together for one day = 1/3 days

(1/3-19/156) days

(52-19/156) days = (33/156) days

11/52 days = 52/11 days

4 whole 8 upon 11
