Question

The angles between two needles at 5.15 O'clock will be :

• A. 60°
• B. 67.5°
• C. 69°
• D. 75°

Answer 1

Answer:

B. 67.5°

Solution:

Formula used:

Angle = | (11/2) × M - 30 × H |

Calculation:

Given, M = 15, H = 5

Put all the values in the given formula,

⇒ Angle = | (11/2) × 15 - 30 × 5 |

⇒ Angle = | 82.5 - 150 |

⇒ Angle = | -67.5 |

⇒ Angle = 67.5

Here, The angles between two needles at 5.15 O'clock will be "67.5".

Hence, the correct answer is "Option (B)".
