Question

How many children are there in the row of children facing South ?

Statement I. P who is fifth from the left end is eighth to the left of Q who is twelfth from the right end.

Statement II. R is fifth to the left of N who is seventh-from the right end and eighteenth from the left end.

• 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

Answer 1

The correct option is C

If the data either in statement I alone or in statement II alone are sufficient to answer the question

Since 8${}^{th}$ to the left of 12${}^{th}$ from the right is 20${}^{th}$ from the right, so from I, we know that P is 5${}^{th}$ from left and 20${}^{th}$ from right i.e. there are 4 children to the left and 19 to the right of P. So, there are (4 + 1 + 19) i.e.24 children in the row. From II, N is 7${}^{th}$ from right and 18${}^{th}$ from left end of the row. So, there are (6 + 1 + 17) = 24 children in the row.
