Question

of the members of a student choir, 60% are boys. if there are 21 boys in the choir, how many members does the choir have in total? a 33 b 35 c 42 d 53

Explanation:

Step1: Define total members

Let total members be \( x \).

Step2: Set up equation

60% of \( x \) is 21, so \( 0.6x = 21 \).

Step3: Solve for \( x \)

Divide both sides by 0.6: \( x=\frac{21}{0.6}=35 \).

Answer:

B. 35
