There block, A, B and C are lying on a smooth horizontal surface, as shown in figure. A and B have equal masses, m while C has mass M. A is a given an initial speed 
towards B due to which it collides with B perfectly inelastically. The combined mass collides with C, also perfectly inelastically 5/6th of the kinetic energy is lost in whole process. What is value of M/m?
