Question

A point is 12 units away from the vertical plane and profile plane 15 units away from horizontal plane in 1st quadrant then the projections are drawn on paper the distance between the front view and side view of point is ________________

(a) 27

(b) 15

(c) 12

(d) 24

This question was addressed to me in an online quiz.

Question is from Projection of Points in First Quadrant topic in portion Projection of Points of Engineering Drawing

Answer 1

Right answer is (d) 24

To explain I would say: Since the point is 12 units away from the profile plane the distance from the point to xy reference line will be 12 units. And then the point is at a distance of 12 units from the profile plane the distance from reference line and point will be 12, sum is 24.
