Explanation

By examining the pattern of beginning times for the three types of appointments, you can see that the times will coincide when the number of minutes after 8:00 in the morning is a common multiple of 30, 25, and 50. The least common multiple of 30, 25, and 50 is 150, which represents 150 minutes, or 2.5 hours. So the times coincide every 2.5 hours after 8:00 in the morning, that is, at 10:30 in the morning, at 1:00 in the afternoon, and so on. The correct answer consists of Choices C and H.

The numbers are 30, 25 and 50.

the common multiples of 30,25 and 50 are 150 min or 2 hours 30 min and 300 min or 5 hours

Time starts from 8:00. After 2.30 hr the time is 10.30 and after 5 hours it is 1.00 pm.

So the answer is C and H

i find the question rather senseless to be honest. Nowhere does it state that the times need to coincide..confusing
