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)".
