Find the ODD one out from the given options.
Correct Answer: A.
Explanation: To solve the problem, first express the relationship between a and b as an algebraic equation. Given that 20% of a = b, this can be written as: 0.2 \* a = b The goal is to determine what b% of 20 equals in terms of a. Substituting the expression for b into the second part of the problem: (b / 100) \* 20 \= (0.2 \* a / 100) \* 20 By rearranging and simplifying the numbers: \= (0.2 \* 20 / 100) \* a \= (4 / 100) \* a \= 4% of a Therefore, b% of 20 is equivalent to 4% of a.
