If n lines are drawn in a plane such that no two of them are parallel and no three of them are concurrent, such that these lines divide the planein 67 parts, then find number of different points at which these lines will cut.

If n lines are drawn in a plane such that no two of them are parallel and no three of them are concurrent, such that these lines divide the plane in 67 parts, then ffind number of different points at which these lines will cut.

If n lines are drawn in a plane such that no two of them are parallel and no three of them are concurrent, then find number of different points at which these lines will cut.

If 20 lines are drawn in a plane such that no two of them are parallel and so three are concurrent,in how many points will they intersect each other?

25 lines are drawn in a plane. Such that no two of them are parallel and no three of them are concurrent. The number of points in which these lines intersect, is:

25 lines are drawn in a plane. Such that no two of them are parallel and no three of them are concurrent. The number of points in which these lines intersect, is:

If 10 lines are drawn in a plane such that no two of them are parallel and no three are concurrent, then the total number of points of intersection are

If 20 lines are drawn in a plane such that no two of them are parallel and so three are concurrent, in how many points will they intersect each other?
