Question

If the maximum and the minimum number of points of intersection of three lines are A and B respectively, then find the value of A + B.

• A. 5
• B. 4
• C. 6
• D. 3

Answer 1

The correct option is D 3

Three lines can intersect at 3 points (Maximum)

So, A = 3.

Minimum number of points of intersection of three lines will be 0, if lines are parallel to each other.

So, B = 0.


Hence, A + B = (3 + 0) = 3.
