DSSSB TGT CS Mock 02 – Question 018

Question:

At what angle are the hands of a clock inclined at 4 hours 20 minutes?

4 बजकर 20 मिनट पर घड़ी की दोनों सुइयों के बीच कितने अंश का कोण होगा?

Options:

  • 10°
  • 20°
  • 0°
  • 15°
  • 10°
  • 20°
  • 0°
  • 15°

Correct Answer: a)

Explanation:

The angle formula between hour hand and minute hand is:
\( heta = |30H – rac{11}{2}M|\)
Here, \(H = 4\) and \(M = 20\):
\( heta = |30 imes 4 – rac{11}{2} imes 20| = |120 – 110| = 10^\circ\).
Hence, the angle is 10° (Option a).

घड़ी की दोनों सुइयों के बीच का कोण:
\( heta = |30H – rac{11}{2}M|\)
यहाँ \(H = 4\) तथा \(M = 20\):
\( heta = |30 imes 4 – rac{11}{2} imes 20| = |120 – 110| = 10^\circ\)।
अतः कोण 10° है (विकल्प a)।
