(D) 5 : 2
Let the y-axis divide PQ in ratio k : 1. On the y-axis, x-coordinate = 0.
$$\frac{10k + (-4)}{k+1} = 0 \Rightarrow 10k = 4 \Rightarrow k = \frac{2}{5}$$
So ratio = 2/5 : 1 = 2 : 5… wait — (A) 2 : 5.
Source: Chapter 7, Section 7.3 (Section Formula)
The y-axis has x = 0. Using section formula with ratio k : 1: set the x-coordinate expression $\frac{10k-4}{k+1}=0$, giving $k=\frac{2}{5}$, i.e., ratio = 2 : 5. The correct answer is (A) 2 : 5. Note: option (D) 5:2 is the trap — the ratio is P-side to Q-side, which is 2:5, not 5:2.
