Question

Arrange the measuring chains in their increasing length :
A. Engineers chain
B. Metric chain
C. Surveyor chain
D. Revenue chain
E. Bigha chain
Choose the correct answer from the options given below :

• A. E $<$ D $<$ C $<$ B $<$ A
• B. A $<$ B $<$ C $<$ D $<$ E
• C. E $<$ C $<$ D $<$ B $<$ A
• D. A $<$ C $<$ B $<$ D $<$ E

Hint:

Surveying Chains Reference Lengths: - Revenue Chain = $33\text{ ft}$ (16 links) - Gunter's Surveyor's Chain = $66\text{ ft}$ (100 links) - Metric Chain = $30\text{ m}$ ($98.4\text{ ft}$) - Engineer's Chain = $100\text{ ft}$ (100 links)

Answer 1

The Correct Option is A

Step 1: Understanding the Question:
The question asks to arrange various survey chains in ascending order of their physical lengths.

Step 2: Standard Lengths of Surveying Chains:

• E. Bigha chain: Traditiol regiol land survey chain (typically $10--20\text{ ft}$ or $\approx 20\text{ ft}$). Shortest chain length.
• D. Revenue chain: Standard length is $33\text{ ft}$ consisting of 16 links ($2.0625\text{ ft per link}$).
• C. Surveyor's chain (Gunter's chain): Standard length is $66\text{ ft}$ consisting of 100 links ($0.66\text{ ft per link}$).
• B. Metric chain: Commonly $30\text{ m}$ length ($\approx 98.42\text{ ft}$).
• A. Engineer's chain: Standard length is $100\text{ ft}$ consisting of 100 links ($1\text{ ft per link}$). Longest chain listed.

Step 3: Detailed Explation & Length Order:

• Expressing all chain lengths in feet for comparison: Bigha chain (E: \approx 20 ft) $<$ Revenue chain (D: 33 ft) $<$ Surveyor chain (C: 66 ft) $<$ Metric chain (B: 30 m \approx 98.4 ft) $<$ Engineer chain (A: 100 ft)
• In terms of letters: \[ E < D < C < B < A \]
• Matches option (A).

Step 4: Fil Answer:
The correct ascending order is E $<$ D $<$ C $<$ B $<$ A. Therefore, option (A) is correct.
