Find the greatest of the numbers a, b, c and d. (I) a - 40 = b - 50 (II) c - 60 = d - 70
AStatement (I) alone is sufficient
BEven together not sufficient
CBoth statements together are sufficient
DStatement (II) alone is sufficient
Answer & Solution
Correct answer: B. Even together not sufficient
1. (I) a - b = -10, so b = a + 10. Nothing about c or d.
2. (II) c - d = -10, so d = c + 10. Nothing about a or b.
3. Together we get b > a and d > c, but a vs c (and hence b vs d) is unknown.
4. Additional data required.
