Answer 1

Answer:

16 days

Step-by-step explanation:

P can do work in 10 days: P can do 1/10 of work in one day

Q can do work in 35 days: Q can do 1/35 of work in one day

If they work on alternate days they will complete:

• 1/10+1/35= 9/70 part of work in 2 days

and in average they will complete:

• 9/70:1/2=9/140 of work in one day

To complete work they need:

• 1:(9/140)=140/9=15.6 days, so if rounded 16 days

Hope it helps
