How many times the hands of a clock are at right angle in a day?

44

Answer :- (C) 44

We know that ,

The two hands of a clpck form a right angle after every \(\frac{360}{11}\) minutes

Total number of minutes in a day = 24 × 60 = 1440 minutes

Number of times the two hands will form a right angle in a day

= 1440 ÷ \(\frac{360}{11}\)

=  \(\frac{ (1440 × 11)}{360}\)

= 4 × 11

= 44 times
