Question

how many times are the hands of a clock at right angle between 2 o' clock to 7 o 'clock ​

Answer 1

Answer:

At 3 O Clock it will be forming 90' angle

Answer 2

As we know between 2o’clock to 7o’clock there are in total 6 digits including 2 & 7
Thus the total angle formed at it is of 180 degrees.
Hence we also know there are in total two 90 degrees that together can form a total of 180 degrees.

Thus 2 times the hands of a clock are at 90 degrees between 2o’clock and 7o’clock
