Question

A, B, C, D and E are five rods. E is longer than A which is longer than C and lighter than C, which is lighter than D. B is shorter than D, and heavier than it. E is longer than D, and heavier than it.

If B is the heaviest of all, then which of the following can be the lightest of all the five rods?

Accepted Answer

B. Comparing the rods on the basis of weight: - $A$ is lighter than $C$, which is lighter than $D$: $D > C > A$ - $B$ is heavier than $D$: $B > D$ - $E$ is heavier than $D$: $E > D$ It is given that $B$ is the heaviest. Combining the above statements gives: $$B > E > D > C > A$$ Thus, $A$ is the lightest of all five rods.
