Answer 1

Answer:

Step-by-step explanation:

A can do 1/4 of work in 5 days .

therefore to complete 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 .

therefore to complete the work is 1/5 / 6/1 which is 1/5 x 1/6 = 30 days .

therefore 1/20 + 1/30 = 3/60 + 2/60 = 5/60

therefore 5/60 of work in one day or by ( simplified ) 1/12

therefore 1/12 of the total work in one day .

therefore it will take 12 days to complete the total number of work .
