The solution:
There are 2 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 additions to Y are a) L,M and N(53) b)L,M and I(60)
c)I,M and N(55) and d) I,L and N(57)

so the answers..
1-d
2-b
3-a
4-c

solve this

a corporate business man has two cubes on his office desk. every day he arranges both cubes so that the front faces show the current day of the month. what numbers are on the faces of the cubes to allow this?
Note: You can't represent the day "7" with a single cube with a side that says 7 on it. You have to use both cubes all the time. So the 7th day would be "07".

this also

you're a cyborg in a pistol duel with two other cyborgs. you have been programmed to fire pistols with an accuracy of 33%. the other two cyborgs shoot with accuracies of 100% and 50%, respectively. the rules of the duel are one shot per-cyborg per-round. the shooting order is from worst shooter to best shooter. thus, you go first, the 50% guy goes second, and the 100% guy goes third; repeat. if a cyborg dies, we just skip his or her turn, obviously. what should you shoot at in round 1 to maximize your chances of survival over time?

So we conclude that Wilson is the Prom Queen(ie with 800 votes). With the given equations, we arrive at the following figures
Monica =640 votes, Young = 320 votes From the remaining sum we also arrive at Nina = 240 votes, Torres = 480 votes, Lara = 720 votes.

Now with the data (ie. who is not who ) the final answer is derived.

Nina (Roman) = 240votes
Heidi (Young) = 320 votes
Jana (Torres) = 480 votes
Monica (Vincent) = 640 votes
Lara (Stone) = 720 votes
Kerrie (Wilson) = 800 votes
