Question

What is the angle made by the hour and minute hands of the clock given above?

• A. ${60}^{\circ }$
• B. ${90}^{\circ }$
• C. ${100}^{\circ }$
• D. ${120}^{\circ }$

Answer 1

The correct option is B ${90}^{\circ }$

The angle between any two consecutive numbers on the clock is $\frac{360}{12}={30}^{\circ }.$

There are three ${30}^{\circ }$ angles in the given angle as shown below:


$\therefore$ The angle made by the hands of the clock is $3\times {30}^{\circ }={90}^{\circ }.$
