Let the total number of people who responded to the advertisement be \(= T\)
\(60\)% of \(T\) were interviewed on phone \(= \frac{60}{100}*T\)
\(20\)% of \(60\)% of \(T\) were asked to come to the company for personal interview, that is \(3\).
Therefore; \(20\)% of \(60\)% of \(T = 3\)
\(\frac{20}{100}*\frac{60}{100}*T = 3\)
\(T = \frac{3*100*100}{20*60} = 25\)
Answer: C
