Question

Maximum and minimum number of points of intersection of three lines are A and B respectively. Then A+B = ?

• A. 3
• B. 4
• C. 5
• D. 6

Answer 1

The correct option is B 4

Three lines can intersect at 3 points (Maximum)

So, A = 3

Minimum number of points of intersection of three lines will be 1

So, B = 1

Hence, A + B = (3 +1) = 4.
