How many times the hands of a clock are at right angle in a day?
Answer & explanation
Correct answer: option 3
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
