Answer & Solution

Correct Answer

(C) -1 : 4

Step-by-step Solution

Detailed explanation

Let the ratio is \(\lambda: 1\). Equation of plane \(3 x+2 y+z=4\) ...(i) By section formula, coordinates of \(P=\left(\frac{-4 \lambda+2}{\lambda+1}, \frac{5 \lambda-4}{\lambda+1}, \frac{-6 \lambda+3}{\lambda+1}\right)\) which lies on the plane…
