Question

Q.2.Where will the hand of a clock stop if it
(a) starts at 12 and makes 1/2 of a revolution, clockwise?
(b) starts at 2 and makes 1/2 of a revolution, clockwise?
(c) starts at 5 and makes 1/4 of a revolution, clockwise?
(d) starts at 5 and makes 3/4 of a revolution, clockwise?

Answer 1

a) The clock hand will stop at 6, b) The clock hand will stop at 8, c) The clock hand will stop at 8, d) The clock hand will stop at 2

Let's understand the

⇒ 1 revolution = 12 hours

Using the unitary method, we have

1/2 of a revolution = 12/2 = 6 hours

1/4 of a revolution = 12/4 = 3 hours

3/4 of a revolution = 3 × 12/4 = 9 hours
