pls help! m really struck at this.

i cud only get b cleared test 1 n 3 ,c cleared 2 n 3, d cleared 2 n 4 and a cleared 1.how to proceed after this.

QUES 93
There are four candidates for an award- A, B, C and D
Only one of the four candidates has cleared both Tests I and II
Only one candidate has cleared both Tests I and III.
Only one candidate has cleared both Tests I and IV.
Only one candidate has cleared both Tests II and III.
Only one candidate has cleared both Tests II and IV.
Only one candidate has cleared both Tests III and IV.
Both A and B had cleared Test I.
Both C and D had cleared Test II.
Both B and C had cleared Test III.
D had cleared Test IV.
The award went to the candidate who had cleared more tests than any other candidate.
The award was given to:
a) A
b) B
c) C
d) D

A does not clear 3 (Only 1 cleared test I and III, which is b itself)
D does not clear 3 (Only 1 cleared test II and III, which is c)
C does clear 3, but does not clear IV since (Only 1 clears II and IV, which is d)
Hence b clears IV, (Only 1 clears test III and IV) since C has not cleared III (Only 1 clears II and III, which is d)

Hence b has 3 cleared, and all others have at least 1 not cleared, thus at this point we may as well say that b is the answer (since the answer must be one of the 4 i.e a,b,c,d)
