The question below is followed by two statements numbered I and II. Decide whether the data given in the statements are sufficient to answer the question.
Some students are standing in a single row. How many students are there in the row?
I. Meena is 12th from the left end of the row.
II. Raju is 9th from the right end of the row and stands somewhere to the right of Meena.
Answer & explanation
Correct answer: option 4
The correct answer is Option (4) → Neither statement I nor statement II is sufficient, even together.
The total in a row can be found from two positions only when the number of students between them is also known.
Statement I alone:
It gives Meena’s place from one end only: not sufficient
Statement II alone:
It gives Raju’s place from one end only: not sufficient
Both together:
Meena has 11 students to her left; Raju has 8 students to his right
If Raju stands just after Meena, the total is \(11+1+1+8=21\)
If 4 students stand between them, the total is \(21+4=25\)
The number between them is not given, so the total is not fixed: not sufficient even together
