How many times do the hands of a clock coincide in a day?
घड़ी की सुइयां दिन में कितनी बार मिलती हैं?

Options

A. 24
B. 22
C. 21
D. 20

Answer

B

Explanation

From the properties of the clock, we know that hands of a clock coincide once in every hour but between 11 O.clock and 1 O.clock they coincide only once. Therefore, the hands of a clock coincide 11 times in every 12 h. Hence. they will coincide `(11 xx 2) = 22` times in 24 h.
89 h or this clock = 90 h of the correct clock Therefore. it is clear that in 89 h this clock loses 1 h and hence. the correct time is 11 :00 pm when this clock shows 10:00 p
