As per the given data

A task is completed by 30 persons in 4 days

we are supposed to find In how many days the same will be completed by 40 persons

Task is completed by 30 persons in 4 days, it mean

30 person does one fourth of the work in one day

1 person does
(1)/(4*30)=(1)/(120)th of the work in one day

So back to previous step,

work done by 40 person in one day =
40*(1)/(120) =(1)/(3)

Hence the number of days required to complete the work by 40 person =3
