In a certain code language, ‘DUST’ is coded as 16 and ‘EARTH’ is coded as 25. How will ‘MAN’ be coded in the same language?

Correct option is B

In this question the logic is square of the total no of alphabet in the given word-
DUST → 4² = 16
EARTH → 5² =25
Similarly,
MAN → 3² = 9
Therefore, the correct answer is (b).
