How often are the hands of the clock at right angle everyday?

We know that , In every hour there are two positions in which hands are at right angle. Each of these positions is repeated 11 times in every 12 hours. ∴ In every 12 hours, hands are at right angles 11 + 11 = 22 times and in a day hands are at right angles 22 + 22 = 44 times.

44

Step-by-step explanation:

In every hour there are two positions in which hands are at right angle.

Each of these positions is repeated 11 times in every 12 hours.

In every 12 hours, hands are at right angles 11 + 11 = 22 times and in a day hands are at right angles 22 + 22 = 44 times.
