`        10 circles and 4 straight lines interset with each other . What is the maximum number of possible points of intersection ?`
8 years ago

147 Points
```										Dear avinava
1 intersection of circle
2 circcle can intersect each other at maximum 2 point.
so 10 circle intersect each other =10c2 *2 points

2 intersection of lines
2 lines can intersect each other at max 1 point
so 4 lines intersect each other = 4c2  points
3 intersection of line and circle
a line can intersect a circle at max 2 point
total intersection =10c1 *4c1 *2 points

final answer is 10c2 *2    +  4c2   +   10c1 *4c1 *2     points
