(1) He answered 3/4 of the odd numbered questions in the first half correctly - No information about second half. Insuff.

(2) He answered 7 more questions correctly in the first half than in the second half - No information about the first half. Insuff.

(1) & (2) together:
Only odd numbered questions of first half can be calculated. No info. about even numbered questions. Insuff.

Ans: E.
