How many times in a day, are the hands of a clock in straight line but opposite in direction?
20
22
24
48
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'clcok only).

So, in a day, the hands point in the opposite directions 22 times.

In every hour, the two hand are once in opposite direction like:

12:30.
1:35.
2:40.
3:45.
4:50.
5:55.
6:00.
7:05.
8:10.
9:15.
10:20.
11:25.

Which means in 12 hrs, it is 12 times and in 24 hours its 24 times.

To find a straight angle, opposite 180^ is 60/11*(t+/-3).

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.

@Nitesh Nandwana,

What is that due to the loss of 2 hour?

I don't know why its answer is 22. I think it should be 24.

According to me,

Only 2 times in a day it happens mathematically. Actually, because for this there should be 180 degree difference between both hands and when hour hand travels 1 degree minute hand travels 12 degree so only 6 o clock it happens that actully difference between both hands is 180 degree. So answer is 2 times in a day.
