घड़ी में (4:40) पर घंटे और मिनट सुई के बीच छोटा कोण कितना है?
What is the smaller angle between the hour hand and minute hand at (4:40)?
Explanation opens after your attempt
C. \(100^\circ\)
Concept
At (4:40), the minute hand is at \(240^\circ\) and the hour hand is at \(140^\circ\), so the difference is \(100^\circ\). The hour hand moves \(0.5^\circ\) per minute.
Why this answer is correct
The correct answer is C. \(100^\circ\). At (4:40), the minute hand is at \(240^\circ\) and the hour hand is at \(140^\circ\), so the difference is \(100^\circ\). The hour hand moves \(0.5^\circ\) per minute.
Exam Tip
(4:40) पर मिनट सुई \(240^\circ\) और घंटे सुई \(140^\circ\) पर होती है इसलिए अंतर \(100^\circ\) है। घंटे सुई हर मिनट \(0.5^\circ\) चलती है।
