Asmita reaches school for a meeting 15 minutes before 8.30 am. She reached half an hour earlier than her colleague who is 40 minutes late for meeting. What is the scheduled time of the meeting ?

The correct option is 8.05 am.

Let us break down the problem step-by-step to find the scheduled time of the meeting:

Step 1: Calculate Asmita's arrival time
Asmita reaches the school 15 minutes before 8:30 am.
Asmita's arrival time = 8:30 am - 15 minutes = 8:15 am.

Step 2: Calculate her colleague's arrival time
Asmita reached half an hour (30 minutes) earlier than her colleague.
This means her colleague reached 30 minutes after Asmita.
Colleague's arrival time = 8:15 am + 30 minutes = 8:45 am.

Step 3: Determine the scheduled time of the meeting
We are given that the colleague is 40 minutes late for the meeting.
Therefore, the scheduled meeting time was 40 minutes before the colleague's arrival time.
Scheduled time = 8:45 am - 40 minutes = 8:05 am.

Thus, the scheduled time of the meeting was 8.05 am.
