Question

A clock is started at 12 o’clock noon. By 10 minutes past 5, the hour hand has turned through
1. 145°
2. 150°
3. 155°
4. 160°

Answer 1

Correct Answer - Option 3 : 155°

We know, Angle traced by hour hand in 12 hours = 360º

Angle traced by hour hand in 1 hour = 360º/12

So, Angle traced by hour hand in 5 hours and 10 minutes (31/6 hours) = (360/12 ×31/6)º = 155º

Hence, 155º  is the correct answer.
