Show answer & explanation
Correct answer: D
Answer: 1, 5, 2, 4, 3 (Iron, Aluminium, Copper, Silver, Gold)
Explanation:
Arrange the metals in order of increasing value (cheapest to most expensive). The relative comparisons are:
Iron is the least valuable among the five.
Aluminium is more valuable than iron but less valuable than copper.
Copper is less valuable than silver but more valuable than aluminium.
Silver is less valuable than gold.
Putting these comparisons together gives the final sequence from cheapest to most expensive:
Iron < Aluminium < Copper < Silver < Gold
