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.

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.

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

Yes, at first, I too thought it's 24 but the mistake is we assume that while the min hand is rotating hour is always near any hour but the hour hand also moves as time goes.
Anyone, correct me if I am wrong.

@Dhanancheziayn.
But from 12 to 1'o clock two hands will be in opposite directions once.

@Swetha
There is no need of formula , if you want formula for only this question then i don't think it is good. Instead of memorize any formula for this single question why don't you remember it's answer, it is much better, because if you calculate using formula it'll never give you different answer because it is universal truth.
Anyway I want to share if you aren't getting how it is calculated.
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 simple.

In 12'o clock the two hands are on same direction, then why we are calculating it?
