Show answer & explanation
Correct answer: B
Concept
In a letter-based number analogy, each letter is first converted to its position in the English alphabet (A = 1, B = 2, ..., Z = 26). The first pair shows how those position numbers are transformed into the given result; the same transformation rule must then be applied to the position numbers of the third pair to find the missing term.
Application
Find the alphabet positions of the first pair: N is the 14th letter and W is the 23rd letter, so N/W = 14/23.
Compare 14/23 with the given result 41/32: 14 with its digits reversed is 41, and 23 with its digits reversed is 32. So the rule linking the pairs is: reverse the digits of each alphabet position.
Find the alphabet positions of the third pair: L is the 12th letter and R is the 18th letter, so L/R = 12/18.
Apply the same digit-reversal rule: 12 with its digits reversed is 21, and 18 with its digits reversed is 81.
So L/R : ? becomes 12/18 : 21/81, giving the missing term as 21/81.
Cross-check
Reversing the digits of 21 and 81 back gives 12 and 18 - exactly the alphabet positions of L and R - confirming the transformation was applied consistently in both directions.
