A blacksmith has five iron articles A, B, C, D and E, each having a different weight. (i) A weights twice as much as B. (ii) B weights four and a half times as much as C. (iii) C weights half as much as D. (iv) D weights half as much as E. (v) E weights less than A but more than C.
E is lighter in weight than which of the other two articles ?

Answer: A. A, B

Let C's weight be x. Then, D's weight is 2x. E's weight is 4x. B's weight is 4.5x and A's weight is 9x. So, the order of weights can be A > B > E > D > C.
