Two numbers are respectively \(20\)% and \(50\)% more than a \(3rd\) number. The ratio of the two numbers is:
Answer: B
Let the \(3rd\) number be \(x.\)
Then, first number \(= 120\)% of \(x = \frac{120x}{100} = \frac{6x}{5}\)
Second number \(= 150 \)% of \(x = \frac{150x}{100} = \frac{3x}{2}\)
\(\therefore\) Ratio of first two numbers \(= (\frac{6x}{5} : \frac{3x}{2}) = 12x : 15x = 4:5\)
