There are m points on a straight line AB & n points on the line AC none of them being the point A. Tri- angles are formed with these points as vertices, when A is excluded (ii) A is included. The ratio of number of triangles in the two cases is

There are ten points in a plane. Of these ten points, four points are in a straight line and with the exceptionof these four points, on three points are in the same straight line. Find i. the number of triangles formed, ii the number of straight lines formed iii the number of quadrilaterals formed, by joining these ten points.

The number of lines that can be formed from 12 points in a plane of which 6 points lie on a line is
