| I. Total of the salary of A and C is exact multiple of 8. |
| II. Average of the salary of A, C and D is Rs. 61665. |
A) If the statement I alone is sufficient to answer the question but the statement II alone is not sufficient
B) If the statement II alone is sufficient to answer the question but the statement I alone is not sufficient
C) If both statements I and II together are needed to answer the question
D) If either the statement I alone or statement II alone is sufficient to answer the question
E) If you cannot get the answer from the statements I and II together but need even more data
Correct Answer: B
Solution :
| \[A+B+C+D=Rs.\,\,(4\times 62880)\] |
| From statement II, |
| \[A+C+D=Rs.\,\,(3\times 61665)\] |
| \[\therefore \]B's salary \[=(A+B+C+D)\]'s salary |
| \[-\,\,(A+C+D)'s\] salary |
| Hence, only statement II is sufficient. |
