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.

This hapns evry 65 min(approx)for each case
=>in 1 day 24 hrs=> 24x60 min
Therefore each case hapns (24x60)/65 times each day................= 22(approx)
Therefore total # of times = 22+ 22=44
=>in 1 day 24 hrs=> 24x60 min
Therefore each case hapns (24x60)/65 times each day................= 22(approx)
Therefore total # of times = 22+ 22=44

NO. the answer is 24. If you count the number of hrs in a day i.e. 24. Therefore use to a clock to count it. Its 24 times starting from 12:00 am to 12:00 am again of next day. Thus the answer is 24.

@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.
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.

7 clock in the opposite direction to rotate 180.
Similarly, the opposite direction of the clock 9 180 turned north end figure 3 to 6 are made. Please give me answer in detail.

In every hour, once hour hand and minute hand will be in opposite direction. It means 24 times in a day, but due to loss of 2 hour, they'll be 22 times only.

When minute hands complete full circle in every hour, then how can it be possible that both hands are not in straight line and opposite direction?
Akshaya said:

I have a doubt. You all say the hour and minute hands are in straight line only once between 5 and 7. What about 5:55?

Assume we start with both hands at 12.
the event occurs after every (2*n +1)*6/11 hours....where n=0,1,2....
