If R gets the most, V should be ranked not lower than

According to question,
V always scored more than P.
V > P
P always scored more than Q.
P > Q
∴ V > P > Q
If R Score highest, we have
R >.......> T
If S Score highest, we have
S >.......> Q or S >.......> U
If R gets the most, T ranks lowest and occupies seventh place. Since V always ranks above P and Q, so at the maximum, P and Q will occupy fifth and sixth places.
Hence, V Will not rank lower than fourth.
