At what angle the hands of a clock are inclined at 15 minutes past 5?

58 $\frac { 1^o } { 2 }$

64°

67 $\frac { 1^o } { 2 }$

72 $\frac { 1^o } { 2 }$

Answer : Option C

Explanation :

Angle traced by hour hand in $\frac { 21 } { 4 }$ hrs=[ $\frac { 360 } { 12 }$ x $\frac { 21 } { 4 } ]^o$ =57 $\frac { 1^o } { 2 }$

Angle traced by min. hand in 15 min. =[ $\frac { 360 } { 60 }$ x $15]^o$ = 90°

Required angle =[157 $\frac { 1^o } { 2 }$ ]- 90° = 67 $\frac { 1^o } { 2 }$
