Answer 1

b. Sushma is on time.

Step-by-step explanation:

We are given that Sushma has a dentist's appointment at 7.20 in the evening. While entering the dentist's office, She saw reflection of the wall clock. The hands of the clock read 4:40. She knew that this being the reflection of the clock.

She assumed that she is not one.

Firstly, as we know that the dentist's appointment was at 7:20 pm and the time which she saw in the reflection was 4:40 pm.

This means that she was on time because the reflection of the hour hand at 7 o'clock will be at 4 o'clock and the reflection of the minute hand at 20 minutes will be at 40 minutes.

This shows that Shushma was on time at the dentist's office.
