1. The angle between the minute hand and the hour hand of a clock when the time is 4.20, is:

2.  A. 0° B. 10° C. 5° D. 20°

Answer : Option B

Explanation :

Angle traced by hour hand in $$\frac { 13 } { 3 }$$hrs=[$$\frac { 360 } {1 2 }$$x$$\frac { 13 } { 3 }]^o$$=130°.

Angle traced by min. hand in 20 min. =[$$\frac { 360 } {1 2 }$$x$$20]^o$$= 120°.

Required angle = (130 - 120)° = 10°
