An ordinary Clock becomes 16 minutes fast every day. If it is set right at 9:00 in the morning, then what time will it show at 6:00 in the evening on the same day?

6:06

6:05

6:07

6:12

✅ Correct Option: 1

The clock gains 16 minutes in 24 hours.

From 9:00 AM to 6:00 PM, the actual time elapsed is 9 hours.

The gain in 9 hours can be found using proportion:

Gain $= \dfrac{16 \text{ minutes}}{24 \text{ hours}} \times 9 \text{ hours}$

Gain $= \dfrac{16 \times 9}{24}$

Gain $= \dfrac{144}{24}$

Gain $= 6$ minutes

At actual 6:00 PM, the faulty clock will show:

Time shown $= 6:00$ PM $+ 6$ minutes

Time shown $= 6:06$ PM
