If the score for team Y was less than 110, what could be the score of team X?
There are two cases:-
(1) D,E,H,B in team X and K,G,F in team Y (total=40). So the only possible team Y is K,G,F,L,M,N and I (total=115)
(2) D,E,F in team X and K,G,H,B in team Y (total=55). So the possible addition to Y are:-
a) L,M and N (total=53)
b) L,M and I (total=60)
c) I,M and N (total=55)
d) I,L and N (total=57)
Hence answer option B
