Question

Angle between the hour and minute hand of a clock at 11:15 is___

• A. ${90}^{\circ }$
• B. ${112.5}^{\circ }$
• C. ${120}^{\circ }$
• D. ${150}^{\circ }$

Answer 1

The correct option is B ${112.5}^{\circ }$

Angle made by hour hand with 12 (Reference point) at 11:15 = ${22.5}^{\circ }$
Angle made by minute hand with 12 (Reference point) at 11:15 = ${90}^{\circ }$
But both the hands are on the opposite sides of the reference point.
So, Angle between the hour and minute hand of a clock at 11:15 is ${22.5}^{\circ }$ + ${90}^{\circ }$ = ${112.5}^{\circ }$
