Concept:
Arrange persons based on given positional conditions.
Step 1: Use given conditions.
Shyam is left of Ravi and right of Sachin
Martin is to the right of Ravi
Rajiv is between Ravi and Martin
Step 2: Form core arrangement.
Since Rajiv is between Ravi and Martin:
\[
{Ravi — Rajiv — Martin}
\]
Step 3: Place Shyam and Sachin.
Shyam is left of Ravi and right of Sachin:
\[
{Sachin — Shyam — Ravi — Rajiv — Martin}
\]
Step 4: Answer the question.
Person immediately to the right of Rajiv is:
\[
{Martin}
\]
Hence, the answer is Martin.
