Arranging Chemical reactions into

[Equilibrium]

Metal AX BX CX DX EX
A - + + + +
B + - + - -
C + + - + -
D - - - - -
E + + + + -

Arrange the following metals A,B,C,D and E according to increasing reactivity out of the information
given above. Use The Symbol of greater than (>) in indicating that one metal is more reactive than the other. Ex A>B>E means metal A is more reactive than B and B is more reactive than E.

Dont know were to start...
i just know that E + AX = There is a reaction where E > A etc.

Metal AX BX CX DX EX

B + - + - -
C + + - + -
D - - - - -
E + + + + -

Arrange the following metals A,B,C,D and E according to increasing reactivity out of the information given above.

What information is this? What do the entries (+,-) in this matrix represent?

 

[Equilibrium]

+ means that there is a reaction
- means that there's no reaction

and my diagram is a table... and sorry for that, can't skip it

If a metal A displace out another metal B from another metal's solution (BX), then this means that metal A is more reactive than metal B.

From the first row of the table, we can get A>B, A>C, A>D, A>E.
Then, from the second row, we get, B>A and B>C.
For the third row, C>A, C>B and C>D,
From the 4th row, we can conclude that metal D is the least reactive among the 5 metals.
5th row, E>A, E>B, E>C, E>D.

However, I think there is something wrong with this question, since we get A>B, and B>A, (and many other contradictions) which only one of them can be true.

Can you please check back the question? Thanks.
