Clocks and Calendars Practice Test 1 with solutions

10 minutes to 4 ⇒ 3:50
Angle formed by the minute hand = 50 × 6 = 300°
Angle formed by the hour hand = 90 + 25 = 115°
Angle formed by both the minute hand and the hour hand at 3:50 = 300 - 115 = 185°.
Hence, the reflex angle at 10 minutes to 4 is 185°.
