From the given information, we have 20% of 60% of respondents = 3

# of respondents = 3/(20% of 60%) = 25

The correct answer: C

Hope this helps!

\(3\) people \(= 20\cdot \dfrac{x}{100}\)

\(x= 15\) people called for phone interview

\(15= 60\cdot \dfrac{x}{100}\)

\(x = 25\); had applied / responded to ad

Therefore, C
