OA: E
lc-dl = 8
lb-dl = ?
1) lc-al = lc-bl
a-b = -18 , a-b = 18
c-d = -8 , c-d = 8
Insufficient.
2) a is to the left of d
We dont know if a is positive or negative. Insufficient.
(1) & (2) together
We still dont know if a is positive or negative. We still cannot determine the exact value of a, b or c. Insufficient.
Thus, E is the answer.
