Which of the following statements is/are correct ?
Statements :
I. Q holds second position.
II. Q holds third position.
III. Q holds fourth position.
To solve this problem, we need to determine the relative ranking of students P, Q, R, S, and T based on the information provided in the question.
Given information:
- Q scored more marks than at least two students.
- T scored less marks than S but more than R.
- S scored less marks than P.
- Q did not score the highest marks.
We can analyze this information to arrange the students in order of their marks:
- Since Q scored more than at least two students, Q can be in any position except the 1st and last.
- From "T scored less than S but more than R," we infer:
- S > T > R
- From "S scored less than P," we infer:
- P > S
- Considering Q did not score the highest, Q can be placed in the 2nd, 3rd, or 4th positions.
Using this information, we can deduce potential rank orders:
- If Q is in the 2nd position: P > Q > S > T > R
- If Q is in the 3rd position: P > S > Q > T > R
Both above cases fit the conditions given regarding Q's position, thus allowing Q to be either 2nd or 3rd. Therefore:
- Statement I: "Q holds the second position" is possible.
- Statement II: "Q holds the third position" is also possible.
- Statement III: "Q holds the fourth position" is not possible, as it violates the requirement of Q scoring more marks than at least two other students.
Therefore, the correct answer is: Either statement I or II is true.

- A transformation experiment is performed with two Pneumococcal strains. One strain is resistant to four drugs - A, B, C, and D, whereas the other is sensitive to all the drugs. Both strains are mixed and the mixture is plated on media containing various combinations of the drugs. The colonies obtained on these plates are given below:
Drugs added No. of colonies Drugs added No. of colonies A 1156 CD 786 B 1148 ABC 30 C 1161 ABD 42 D 1139 ACD 630 AB 46 BCD 36 AC 640 ABCD 30 AD 942 BC 51
