Question

Arrange the following words in a meaningful order: 
1. Hectogram     2. Milligram     3. Decagram     4. Tonne    5. Decigram 
 

• A. 4, 1, 5, 3, 2
• B. 2, 3, 5, 1, 4
• C. 2, 5, 3, 1, 4
• D. 4, 3, 1, 5, 2
• E. 2, 3, 1, 5, 4

Hint:

To remember the order of metric prefixes, use the mnemonic: \textbf{K}ing \textbf{H}enry \textbf{D}ied \textbf{B}y \textbf{D}rinking \textbf{C}hocolate \textbf{M}ilk (Kilo, Hecto, Deca, Base, Deci, Centi, Milli).

Answer 1

The Correct Option is C

Step 1: Understanding the Concept:
The words represent units of mass in the metric system. A meaningful order can be established by arranging them from the smallest unit to the largest unit or vice versa.
Step 2: Key Formula or Approach:
Identify the numerical value of each unit relative to a base unit (gram):

• Milligram (mg) = $0.001$ g
• Decigram (dg) = $0.1$ g
• Decagram (dag) = $10$ g
• Hectogram (hg) = $100$ g
• Tonne (t) = $1,000,000$ g

Step 3: Detailed Explanation:
Arranging from smallest to largest:
1. Milligram (2)
2. Decigram (5)
3. Decagram (3)
4. Hectogram (1)
5. Tonne (4)
The sequence is 2, 5, 3, 1, 4.
Step 4: Final Answer:
The correct meaningful order is 2, 5, 3, 1, 4.
