Let P, Q, R, S, T, U, V, and W represent the eight people.
If all the eight people are to be present on the left bank, it would require at least eight trips. This is because, since the ferry is on the left bank, it will take two trips to bring one person from the right bank to the left bank (one person from left bank will go to the right bank and return with another person from the right bank). If they were to converge on the right bank, the minimum number of trips it would take is 5. T and P from the left bank can go to the right bank first. S has to return with the ferry and take one more person, V, to the right bank. S will travel back and return with W. This will repeat until everyone moves to the right bank. Hence the answer is 5.

Analysis:
- There are 8 people in total, 4 on each bank of the river.
- The ferry can carry a maximum of 2 people at a time.
- Certain preferences are given regarding how the people would like to travel.

Trip 2:
- Tarun returns to the initial bank.

Trip 3:
- Venky and Waqar travel together to the other bank.

Trip 4:
- Pavan and Tarun travel together to the other bank.

Trip 5:
- Qureshi and Ramesh travel together to the other bank.

Final arrangement:
- Pavan, Tarun, Venky, Waqar, Qureshi, Ramesh are on one bank.
- Sanjay and Uday are on the other bank.
Therefore, the minimum number of trips the ferry must make so that all the eight people are present on the same bank is 5 trips.
