A) \[350{}^\circ \]
B) \[355{}^\circ \]
C) \[340{}^\circ \]
D) \[365{}^\circ \]
Correct Answer: A
Solution :
Formula \[\mathbf{=(CM-5H)\times 6}-\frac{\mathbf{M}}{\mathbf{2}}\] [M = Minutes, H = Hours] \[\theta =(20-5\times 4)\times 6-\frac{20}{2}\] \[\theta =(20-20)\times 6-10=0\times 6-10\] \[\theta =10\] is a smaller angel. Bigger angle = 360 - smaller angle (10) \[\theta =360-10\Rightarrow \underline{\mathbf{350{}^\circ }}\]
