Correct option is B
Step 1: Determine Rankings When R is the Highest
If R scores the highest, then:
The remaining students (S, V, P, Q, U) will fill positions 2nd to 6th. We know:
Step 2: V's Minimum Ranking
Final Answer:
B: Fourth
- Seven students: P, Q, R, S, T, U, V.
- No two students get the same marks.
- V always scored more than P:V>PV > PV>P.
- P always scored more than Q:P>QP > QP>Q.
- Each time:
- Either R scores the highest and T gets the least, or
- S scores the highest and U or Q scores the least.
- R is ranked 1st.
- TTT is ranked 7th (as TTT gets the least when RRR is the highest).
- V>P>QV > P > QV>P>Q: V must rank higher than both P and Q.
- The rules do not explicitly state a direct relationship between V, S, and U other than the possibility of U being ranked low.
- R is 1st, and TTT is 7th.
- V > P > Q ensures that VVV is ranked higher than P and Q, which are at least 5th and 6th, respectively.
- Therefore, VVV cannot be ranked lower than 4th, as it must be ahead of P and Q.
