The greatest possible number of points of intersection of 8 straight lines and 4 circles in a plane is
(a) 32 (b) 64 (c) 76 (d) 104
Correct option (b) 64
Explanation:
One st. line can intersect 4 circles at maximum 8 pts. So 8 st. lines can intersect at 64 pts. Note the language of the question. It is asking only those pts and not pts created by intersection of 2 st lines or 2 circles.
