Answer:
90
Step-by-step explanation:
Let the total work be 180 units
Both of them together take 60 days
So P & Q finish 3 units of work in a day
P is twice as good as Q
P = 2Q
and we know that P+Q = 3
2Q+Q = 3
Q = 1 unit/day, P= 2 units/day
If P alone had to finish the work, he'll take 180/2 = 90 days
