Gold number of protective colloids K, L, M and N are 0.7, 0.02, 0.3 and 0.002 respectively. The correct order of their protective power is
The straight lines L1,L2,L3 are parallel and lie in the same plane. A total number of m points are taken on L1,n points on L2, k points on L3. The maximum number of triangles formed with vertices at these points are
The values of ‘n’ for N, M, L and K respectively are:
