 If + = x ,  = ÷ , x = + , ÷ =  , then which is the correct equation out of the following ?

 18 ÷ 6 + 4  2 ÷ 3 = 22
 18 + 6  4 x 2 ÷ 3 = 26
 18 x 6  4 + 7 x 8 = 47
 18  6 x 7 ÷ 2 + 8 = 63

Direction: In these question, relationship between different element is shown in the statements. These statements are followed by two conclusions.
 Statements:
A > B > C, D > E > F, D > C
Conclusions:
I.E > C II. F > B

 If only conclusion I follows
 If only conclusion II follows
 If either conclusion I or II follows
 If neither conclusion I nor II follows
 If both conclusion I and II follow.

A > B < C < D > E > F
E and C can't be compared. Hence II does not follow.
Z and J can't be compared. Hence I does not follows. Consequently II does not follows either.Correct Option: D
A > B < C < D > E > F
E and C can't be compared. Hence II does not follow.
Z and J can't be compared. Hence I does not follows. Consequently II does not follows either.
