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 children are standing in a single row. How many children are there in the row?
I. Kabir is 15th from the left end of the row.
II. Isha is 7th from the right end of the row and stands somewhere to the right of Kabir.
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 children between them is also known.
Statement I alone:
It gives Kabir’s place from one end only: not sufficient
Statement II alone:
It gives Isha’s place from one end only: not sufficient
Both together:
Kabir has 14 children to his left; Isha has 6 children to her right
If Isha stands just after Kabir, the total is \(14+1+1+6=22\)
If 3 children stand between them, the total is \(22+3=25\)
The number between them is not given, so the total is not fixed: not sufficient even together
