At what angle the hands of a clock are inclined at 3 hours 40 minutes ?
घड़ी की सूइयां किस कोण पर 3 घंटे 40 मिनट पर झुकी होती हैं

Options

A. `150^(@)`
B. `120^(@)`
C. `45^(@)`
D. `130^(@)`

Answer

D

Explanation

From the formula, `theta=11/2m-30h`.
`" "[because 11/2m gt 30h]`

According to the question,
Here, m = 40, h = 3
So, `theta=11/2 times 40-30 times 3=220-90=130^(@)`
So, the hands of a clock are inclined at 3 hours 40 minutes at `130^(@)`.
