Answer 1

Answer:

20days

Step-by-step explanation:

LCM of 20,30,60=60

so Aman does 60/20=3unit

Abhishek does 60/30=2unit

Albert does 60/60=1unit

In Four days total no of units=3(day 1)+2(day2)+1(day3)+2+1+3(4days)=12days

No.of set more required to complete work 60/12=5

5more set of 4 (5*4)=20days

Answer=20days
