A small problem

Hi *,

For some tasks both X & Y were evaluated.
Out of 200 X got 75 of A, 105 of B+ and 20 of B.
Similarly Y got 60 of A, 130 of B+ and 10 of B.
A has more weight then B+ and B+ has more weight than B.
I don't know what is A, B+ and B actually and hoe much their weight differ.
Can we find better of X and Y based on this data? If yes who is better ?

X Y
A 75 60
B+ 105 130
B 20 10


TIA,

B<B+<(3A+2B)/5 => X>Y
B+=(3A+2B)/5 => X=Y

(3A+2B)/5<B+<A => X<Y
