D. 135º
[expand title=”Show Answer” swaptitle=”Hide”]
Correct Answer : C
Explanation :
Angle traced by hour hand in 12 hrs. = 360º.
Angle traced by it in 11/3 hrs = (360/12 x 11/3)º = 110º
Angle traced by minute hand in 60 min. = 360º.
Angle traced by it in 40 min. = (360/12 x 40)º = 240º.
Required angle (240 – 110)º = 130º.
