Question

Let the image of the point P(1, 2, 3) in the line L : x-6/3 = y-1/2 = z-2/3 be Q. let R (α,β,γ) be a point that divides internally the line segment PQ in the ratio 1 : 3. Then the value of 22 (α+β+γ) is equal to

Answer 1

Correct answer is 125

Let M be the mid-point of PQ

Since R is mid-point of PM

22 (α+β+γ) = 125
