Step 1: Calculate the on-time return rate for each student.
Sara: 6/8 = 75%; Michael: 5/5 = 100%; Ravi: 7/10 = 70%; Tim: 6/6 = 100%.
Step 2: Michael and Tim both have 100% on-time return rates.
Step 3: Tie-break by number of books borrowed — Tim borrowed 6, Michael borrowed 5. Tim read more with the same perfect return rate.
Answer: Tim
Correct answer: Tim
