13.
How many times in a day, are the hands of a clock in straight line but opposite in direction?
Answer: Option
Explanation:
The hands of a clock point in opposite directions (in the same straight line) 11 times in every 12 hours. (Because between 5 and 7 they point in opposite directions at 6 o'clock only).
So, in a day, the hands point in the opposite directions 22 times.

Great this question was one of the mind buzzing.
And to tell you if you are taking opposite hands of watch as 12:30, 1:35 so on, then I am afraid your are wrong.
Because the hour hand won't be exactly on 12 if its 12:30, it will be at mid way of 12 and 1; and if its midway how can you put minute hand of watch on 12:30.
It should be somewhere around 12:32.5. Rest you can check manually.

Answer is 22. Just try by yourself. Use a clock and start rotating its hands. You'll find your answer.

@Anil Kumar.
7:5^5/11
8:10^10/11
9:16^1/11
10:54^6/11 & again
12:30 (by this 12 hrs are completed)
After 9:16, it is not at 10:54. it is at 10:21 and then 11:27.
So in total, 22 times.

8:10^10/11

It's not a straight line at 12:30. It's a straight line roughly around 12:33 because the hour hand will be halfway between 12 & 1 at 12:30. So 12-4 get 1 occurrence each. 5 does not get an occurrence as the hands won't line up perfectly until 6:00 sharp. 6 through 11 get 1 occurrence each. That means that in that 12-hour period, we get 11.
Repeat for the following 12 to get a 24-hr day.
