Question

How many times are, the hands of a clocks perpendicular in a day ?

• A. 42
• B. 48
• C. 44
• D. 46

Answer 1

Answer: (C)

44

In $12$ hrs. the hands of the clock will be perpendicular to each other for $22$ times as in $1$ hr. time the hands of the clock will be at right angles for $2$ times but between $11$'O clock and $1$'O clock they will be at right angles only twice. Therefore, in $24$ hrs. they will be at right angles to each other $44$ times.
