Answer 2

Given:

P(1, 2)

the line joining of A(–2, 1) and B(7, 4)

$\text { Let the required ratio be } \mathrm{K}: 1$

$\text { By Section Formula, }\left[\frac{m x_{2}+n x_{1}}{2}, \frac{m y_{2}+n y_{1}}{2}\right]$

$\frac{7 \mathrm{~K}-2}{\mathrm{~K}+1}=1$

7k - 2 = k + 1

7k - k = 1 + 2

6k=3

$k=\frac{3}{6}\\k=\frac{1}{2}$

k=1:2

The correct option is "1"

Hence the answer is 1 : 2
