Question:
What is the angle between the two hands of a clock at 7:20?
7:20 बजे घड़ी की दोनों सुइयों के बीच का कोण क्या होगा?
Options:
- \(100^\circ\)
- \(90^\circ\)
- \(110^\circ\)
- \(80^\circ\)
- \(100^\circ\)
- \(90^\circ\)
- \(110^\circ\)
- \(80^\circ\)
Correct Answer: a)
Explanation:
Formula: \(|30H – \frac{11}{2}M| = |30(7) – \frac{11}{2}(20)| = |210 – 110| = 100^\circ\).
कोण = \(|30H – 5.5M| = |30(7) – 5.5(20)| = |210 – 110| = 100^\circ\)।
