Question

Appu can complete a task in 9 days and Misha can do it in 18 days. How long will they
take to complete the task, if both work together?​

Answer 1

Answer:

appu completes work in 9 days

so,work done on one day=1/9

in the same way

work done in one day by misha=1/18

total work =1

now if both works together then,

let no. of days be x

x(1/9+1/18)=1

x/6=1

x=6 days

therefore,appu and misha will complete the task in 6 days together.

hope it helped
