Angle traced by hour hand in \(\frac{125}{12}\) hrs =\(\left(\frac{360}{12}\times\frac{125}{12}\right)^{0}= 312\frac{1}{2}^{0}\)
Angle traced by minute hand in 25 min = \(\left(\frac{360}{50}\times25\right)^{0}=150^{0}\)
So, Reflex angle = 360º – \(\left( 312\frac{1}{2}^{0}-150\right)^{0}=360^{0}-162\frac{1}{2}^{0}=197\frac{1}{2}^{0}\)
