The reflex angle between the hands of a clock at 10.25 is:

180°

192\( \frac { 1^o } { 2 } \)

195°

197\( \frac { 1^o } { 2 } \)

Answer : Option D

Explanation :

Angle traced by hour hand in\(\frac { 125 } {1 2 } \)hrs=[\(\frac { 360 } {1 2 } \)x\(\frac { 125 } {1 2 } ]^o\)=312\( \frac { 1^o } { 2 } \)

Angle traced by minute hand in 25 min =[\(\frac { 360 } {1 2 } \)x\(25 ]^o\)=\(150^o\)

Reflex angle = 360°-\([312\frac { 1 } { 2 } -150]^o\)-162\( \frac { 1^o } { 2 } \)=197\( \frac { 1^o } { 2 } \)
