Question

The priest told the devotee, "The temple bell is rung at regular intervals of $45$ minutes. The last bell was rung five minutes ago. If the next bell is due to be rung at $7:45AM$, then at what time did the priest give this information to the devotee?

• A. $7:40AM$
• B. $7:05AM$
• C. $6:55AM$
• D. None of these

Answer 1

The correct option is B $7:05AM$

Let us assume the bell rang at $xAM$
Now, it rings after every $45min$
The next bell will be rang at $7:45AM$
The priest said it $5min$ after bell was rung.
So, the bell was rang at $7AM$ and priest said it at $7AM+5min=7:05AM$
