Question

P and Q together can built a room in 60 days. If P is twice as good as Q, in how many days will P alone finish his work?​ pls. tell me the whole formula

Answer 1

Answer:

30 days is the correct answer as p and q built in 60 days whlie doubling p and q than time reduce and complete in 30 days

Answer 2

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
