1.
Tim's time = 3/7(Pete's time)
We don't have information about John
This statement alone if not sufficient to give us a definite answer.
2.
Pete's time = 7/3(John's time)
We don't have information about Tim
This statement alone if not sufficient to give us a definite answer.
On combining both the statements, however, we can arrive at a solution.
Hence this is enough to find out which of the 3 has won maximum races.
(Option C)
Tim's time = 3/7(Pete's time)
We don't have information about John
This statement alone if not sufficient to give us a definite answer.

To Find who won the maximum races, we need to be able to compare the ratios.
From Statement 1: Tim won 3/7 as many races as Pete.
This gives us the outcome ratio of races between Time and Pete = 3 : 7
No data is given about John.
Statement 1 Alone is insufficient. Answer options could be B, C or E
From Statement 2: Pete won 7/3 as many races as John.
This gives us the outcome ratio of races between Pete and John = 7 : 3
No data is given about John.
Statement 2 Alone is insufficient. Answer options could be C or E
Combining both Statements: Tim won 3/7 as many races as Pete and Pete won 7/3 as many races as John.
This gives us the outcome ratio of races between Tim and Pete = 3 : 7 and Pete and John = 7 : 3
Combining the 2 ratios, we ratio of races won for T : P : J = 3 : 7 : 3
Since there is a clear answer that Pete has the maximum number of wins, both statements are sufficient.
