Verified by Experts
The correct answer is:
A

Given

The equation of the plane that contains the point (-2,3,5) and is perpendicular to each of the planes 2x + 4y + 5z = 8 and 3x – 2y + 3z = 5 is

Now satisfying the point (- 2,3, 5) in plane P : + 97 = 0 we get.

........(ii)

And using perpendicular condition 2x + 4y + 5z = 8 and we get.

......(ii)

Similarly. ........(iii)

Now solving equation (i), (ii) & (iii) we get,

= 22, = 9& = -16

Hence, = 22 + 9-16=15
