UPSC 2000: An accurate clock shows 8 o’clock in the morning. Through how many degrees will the hour hand rotate when the clock shows 2 o’clock in the afternoon?

(b)144°
(c)168°
(d)180°
Attempt This Question
Not attemptedCorrect Answer: (d) 180°
The hour hand turns 360° in 12 h, i.e. 30° per hour. From 8 a.m. to 2 p.m. is 6 h; hence rotation = 6 h × 30° / h = 180°. Other options correspond to multiplying by 5 h (150°), mis-using 12 h/2.5 (144°) or 5.6 h (168°).
