Four persons, Pavan, Tarun, Venky, and Waqar, are standing on the left bank of a river, whereas another four persons, Qureshi, Ramesh, Sanjay, and Uday, are standing on the right bank of the river. A ferry, which can be used to cross the river and go to the other bank, is present initially on the left bank. The ferry can carry a maximum of two people at a time. However, there must be at least one person in the ferry in order to guide it to the other bank. The travel of the ferry from one bank to the other is called a trip. The eight persons have certain preferences regarding how they would like to travel in the ferry. The following information is known about their preferences:
i. If Pavan is present in the ferry, Tarun must also be present in the ferry.
ii. If Venky travels to a bank on which Sanjay is already present, Sanjay will immediately travel to the opposite bank.
iii. Qureshi will travel in the ferry only when Uday is not present in the ferry.
iv. Venky and Waqar cannot travel together in the ferry.
Q. After the ferry completed three trips, which of the following pairs of persons cannot be on the left bank?
  • a)
    Sanjay, Uday
  • b)
    Ramesh, Sanjay
  • c)
    Pavan, Tarun
  • d)

Qureshi and Uday could not have travelled together in the ferry. Hence, for them to come from right bank to left bank, the ferry would have to make at least two trips from right bank to left bank. Since this is not the case, Qureshi and Uday could not have been on the left bank.

Analysis:
- After the ferry completed three trips, we need to determine which pairs of persons cannot be on the left bank.
- Let's consider the preferences of each person and how they affect the trips.

Trip 1:
- Pavan and Tarun must travel together.
- So, Pavan and Tarun will be in the ferry for the first trip.

Trip 2:
- Venky cannot travel with Waqar.
- Venky will travel with either Qureshi, Ramesh, Sanjay, or Uday.
- Let's assume Venky travels with Qureshi.
- Sanjay will immediately travel to the opposite bank.
- So, Sanjay will be on the ferry for the second trip along with Venky and Qureshi.

Trip 3:
- Since Uday cannot travel with Qureshi, Ramesh, or Sanjay, Uday will travel with Waqar.
- Thus, Uday and Waqar will be in the ferry for the third trip.

Conclusion:
- After three trips, the pairs of persons left on the left bank will be Tarun, Pavan, and the other two persons who did not travel in the three trips.
- Therefore, the pair of persons that cannot be on the left bank are Qureshi and Uday.
