Lets Roses be \(R\), Tulips be \(T\), and Daisies be \(D\).
We need to find \(\frac{R}{D}\) Or \(R:D\)
\(\frac{R}{T} = \frac{3}{2}\)
\(2R = 3T\) ------------ (i)
\(\frac{T}{D} = \frac{4}{5}\)
\(T = \frac{4}{5}D\) --------- (ii)
Substituting value of \(T\) from (ii) to (i), we get;
\(2R = 3*\frac{4}{5}D\)
\(\frac{R}{D} = \frac{6}{5}\)
\(R:D = 6:5\)
