Answer 2

Answer:

15days

Step-by-step explanation:

work done by A in one day is (1/20) of total work...

similarly ,

workdone by B in one day is (1/30)

and of C is (1/60)

let us calculate how much work is done in 3days

3*(1/20) + (1/30) + (1/60) = (1/5)

there fore in every 3days one fifth work is completed so we need to repeat this 5 times to complete the work

there fore number of days taken will be 5*3 = 15 days
