Step-by-step explanation:
A can do 1/4 of work in 5 days .
therfore to complet the work is 1/4 / 5/1 which is 1/4 x 1/5 = 20 days .
b can do 1/5 of work in 6days .
therfore to complete the work is 1/5 / 6/1 which is 1/5 x 1/6 = 30 days .
therfore 1/20 + 1/30 = 3/60 + 2/60 = 5/60
therfore 5/60 of work in one day or by ( simplified ) 1/12
therfore 1/12 of the total work in one day .
therfore it will take 12 days to complete the total number of work .
