Let the numbers of cars sold by different manufactures is as shown below.
P - a
Q - b
R - c
S - d
T - e
$\begin{array}{cccccc}& P& Q& R& S& T\\ B& 0.24a& 0.16b& 0.32c& 0.24d& 0.28e\\ B^{+}& 0.16a& 0.24b& 0.10c& 0.16d& 0.08e\\ C& 0.18a& 0.24b& 0.15c& 0.32d& 0.12e\\ D& 0.36a& 0.20b& 0.35c& 0.24d& 0.48e\\ E& 0.06a& 0.16b& 0.08c& 0.04d& 0.04e\end{array}$
Let the numbers of cars sold by different segments is as shown below.
B - v
$B^{+}$ - w
C - x
D - y
E - z
$\begin{array}{cccccc}& B& B^{+}& C& D& E\\ P& 0.15v& 0.20w& 0.15x& 0.18y& 0.15z\\ Q& 0.05v& 0.15w& 0.10x& 0.05y& 0.20z\\ R& 0.40v& 0.25w& 0.25x& 0.35y& 0.40z\\ S& 0.225v& 0.30w& 0.40x& 0.18y& 0.15z\\ T& 0.175v& 0.10w& 0.10x& 0.24y& 0.10z\end{array}$
From the above two tables, we can say that number of cars sold in the D segment is same as the number of cars sold by manufacture R.
