A) 120 degrees	B) 125 degrees
C) 130 degrees	D) 135 degrees

Answer & Explanation Answer: C) 130 degrees

Explanation:

Angle traced by hour hand in 12 hrs. = 360º.

Angle traced by it in 11/3 hrs= ${(\frac{360}{12} * \frac{11}{3})}^{°}$ = $110^{°}$

Angle traced by minute hand in 60 min. = 360º.

Angle traced by it in 40 min. =(360/60*40) $°^{}$ =240 $°^{}$

Required angle (240 - 110)º = 130º.
