A) \[3:5\]
B) \[3:7\]
C) \[3:4\]
D) \[4:3\]
Correct Answer: C
Solution :
Let point R(x, y) divides the PQ into \[K:1\]and point R lies on the line \[=3x+y-9=0\] \[\therefore \,\,\,\,x=\frac{2K+1}{K+1},\,\,\,y=\frac{7K+3}{K+1}\] Put the value of x and y in the equation of line \[3x+y=9\Rightarrow \frac{6K+3+7K+3}{K+1}=9\] \[13\,K+6=9K+9\Rightarrow 4K=3\] \[K=\frac{3}{4}=\,\underline{\mathbf{3:4}}\]You need to login to perform this action.
