Five boys are sitting in a row. Kajol is sitting in between Piyush and Paresh, while Gogol is sitting in between Ronnie and Piyush. Who is sitting at the extreme right end of the row relative to Gogol?
- APiyush
- BParesh
- CRonnie
- DEither B or C
Solution & Step-by-step Explanation
Let's systematically analyze the conditions given to construct the row layout:
1. "Kajol is sitting in between Piyush and Paresh": This gives us two possible sub-arrangements:
* Pattern X:
* Pattern Y:
2. "Gogol is sitting in between Ronnie and Piyush": This also gives us two sub-arrangements:
* Pattern M:
* Pattern N:
Now, let's link these patterns together to form a full -person row:
* Case 1: Combining Pattern X and Pattern M creates the sequence:
* Case 2: Combining Pattern N and Pattern Y creates the sequence:
Because both row arrangements fully satisfy all the rules, the person sitting at the extreme right can be either Paresh or Ronnie.
1. "Kajol is sitting in between Piyush and Paresh": This gives us two possible sub-arrangements:
* Pattern X:
Paresh - Kajol - Piyush* Pattern Y:
Piyush - Kajol - Paresh2. "Gogol is sitting in between Ronnie and Piyush": This also gives us two sub-arrangements:
* Pattern M:
Piyush - Gogol - Ronnie* Pattern N:
Ronnie - Gogol - PiyushNow, let's link these patterns together to form a full -person row:
* Case 1: Combining Pattern X and Pattern M creates the sequence:
Paresh - Kajol - Piyush - Gogol - Ronnie. Looking from left to right, Ronnie sits at the extreme right end of the row.* Case 2: Combining Pattern N and Pattern Y creates the sequence:
Ronnie - Gogol - Piyush - Kajol - Paresh. Looking from left to right, Paresh sits at the extreme right end of the row.Because both row arrangements fully satisfy all the rules, the person sitting at the extreme right can be either Paresh or Ronnie.
