1. A clock is started at noon. By 10 minutes past 5, the hour hand has turned through:

A. 145º

B. 150º

C. 155º

D. 160º

Solution:

Angle traced by hour hand in 12 hrs =

Angle traced by hour hand in 5 hrs 10 min. i.e.,

\begin{aligned} \frac{31}{6} hrs = {(\frac{360}{12} \times \frac{31}{6})}^{\circ} \\ = 155^{\circ} \end{aligned}
