The question below is followed by two statements numbered I and II. Choose the option that describes whether the statements are sufficient to answer the question.
People are standing in a single queue, one behind another. What is Rekha’s position from the front of the queue?
I. Rekha is 11th from the back of the queue.
II. There are 5 people in front of Gopal, and Rekha stands behind Gopal with exactly three people between them.
Answer & explanation
Correct answer: option 1
The correct answer is Option (1) → The question can be answered by using one of the statements alone, but not by using the other statement alone.
A position from the front needs the count of people ahead of the person.
Statement I alone:
The length of the queue is not given, so the place from the back cannot be turned into a place from the front: not sufficient
Statement II alone:
5 people are in front of Gopal, so Gopal is 6th from the front
Three people stand between Gopal and Rekha, so Rekha is \(6+4=\) 10th from the front: sufficient
Statement II alone answers the question, and statement I alone does not.
