Question

The given question consists of a set of statements. Find out whether the data provided in the statements are sufficient to answer the question and mark the option:

How many people are standing between X and Y in a row ?

Statement I: X is fifteenth from the left end of the row.
Statement II: Y is exactly in the middle and there are ten children standing to his right.

• A. If the data in statement I alone is sufficient to answer the question, while the data in statement II alone is not sufficient to answer the question
• B. If the data in statement II alone is sufficient to answer the question, while the data in statement I alone is not sufficient to answer the question
• C. If the data either in statement I alone or in statement II alone are sufficient to answer the question
• D. If the data given in both statements I and II together are not sufficient to answer the question
• E. If the data in both statements I and II together are necessary to answer the question

Answer 1

The correct option is E

If the data in both statements I and II together are necessary to answer the question

From II, Y being in the middle, there are 10 children to his right as well as to his left. So, Y is 11${}^{th}$ from the left.
From I, X is 15${}^{th}$ from the left.
Thus, on combining both the statements I and II, we conclude that there are 3 children between P and Q.
