Question

A clock is set right at 6 a.m. The clock loses 16 minutes in 24 hours. What will be the true time when the clock indicates 10 p.m. on 4th day?

• A. 11
• B. 8
• C. 10
• D. 9

Answer 1

The Correct Option is A

Step 1: The clock loses 16 minutes every 24 hours. 

Step 2: In 4 days (96 hours), the clock will lose:

\[ \frac{16 \times 96}{24} = 64 \text{ minutes} \]

Step 3: The time shown by the clock at 10 p.m. on the 4th day will be 64 minutes less than the true time. So, the true time is:

\[ 10 \text{ p.m.} + 64 \text{ minutes} = 11:04 \text{ p.m.} \]
