I. Total of the salaries of A and C is an exact multiple of 8.
II. Average of the salaries 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 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 and need even more data

Answer 1

The correct option is B if the Statement II alone is sufficient to answer the question but the Statement I alone is not sufficient

Total salary of A, B, C and D = 4 $\times$ 62880 = Rs 251520.
From Statement II, we can find the total salary of A, C, and D and subtracting it from above value, we can get the salary of B. Also, nothing can be said about the salary of B using Statement I.
