P and Q can finish a work in 15 and 10 days respectively. Q starts the work and leaves it after 5 days. The number of days in which P can complete the work is :

- A6 1/2 days
- B7 1/2 days
- C8 days
- D9 days
- ENone of these
**Explanation:**P's 1 day's work = 1/15

Q's 1 day's work = 1/10

Q's 5 day's work=5/10=1/2

Remaining work = 1-1/2=1/2

So P can do the remaining work in 15/2 days.

Required days = 7 1/2 days

P and Q can finish a work in 15 and 10 days respectively. Q starts the work and leaves it after 5 days. The number of days in which P can complete the work is :

- A6 ½ days
- B7 ½ days
- C8 days
- D9 days
- ENone of these
**Explanation:**P's 1 day's work = 1/15

Q's 1 day's work = 1/10

Q's 5 day's work = 5/10 = 1/2

So, P can do the remaining work in 15/2 days.

∴ Required days = 7 ½ days
