What will be the angle between hour hand and minute hand of the clock at 7:15?
Answer & explanation
Correct answer: option 3
The correct answer is Option (3) → 127.5°
Step 1: Formula for angle
$\text{Angle} = \left| 30H - \frac{11}{2} M \right|$
Where:
- H = hour
- M = minutes
Step 2: Substitute values
- H = 7
- M = 15
$\text{Angle} = \left| 30 \cdot 7 - \frac{11}{2} \cdot 15 \right|$
$= \left| 210 - 82.5 \right|$
$= 127.5^\circ$
