Question

Arrange the following mountain peaks in ascending order of their height. \[ \begin{aligned} A.&\ \text{Annapurna} B.&\ \text{Namcha Barwa} C.&\ \text{Makalu} D.&\ \text{Nanda Devi} \end{aligned} \] Choose the correct answer from the options given below:

• A. D, A, B, C
• B. B, D, A, C
• C. D, B, C, A
• D. B, A, D, C

Hint:

Approximate heights: \[ \boxed{ 7782 < 7816 < 8091 < 8485 } \] Mnemonic: “Namcha, Nanda, Annapurna, Makalu.”

Answer 1

The Correct Option is A

Concept: The heights of the peaks are approximately: \[ \begin{aligned} \text{Nanda Devi} &\rightarrow 7816\ \text{m}, \text{Annapurna-I} &\rightarrow 8091\ \text{m}, \text{Namcha Barwa} &\rightarrow 7782\ \text{m}, \text{Makalu} &\rightarrow 8485\ \text{m}. \end{aligned} \]

Step 1: Arrange from lowest to highest. \[ \boxed{ \text{Namcha Barwa} < \text{Nanda Devi} < \text{Annapurna} < \text{Makalu} } \]

Step 2: Convert into letter sequence. \[ \boxed{ B \rightarrow D \rightarrow A \rightarrow C } \] Hence, \[ \boxed{\text{(B)}} \]
