Three blocks 
and 
are lying on a smooth horizontal surface, as shown in the figure. 
and 
have equal masses, 
while 
has mass 
. Block 
is given an initial speed 
towards 
due to which it collides with B perfectly inelastically. The combined mass collides with 
, also perfectly inelastically. The combined mass
collides with 
, also perfectly inelastically if 
th of the initial kinetic energy is lost in whole process. What is value of 
?

Apply LMC (Linear Momentum Conservation)
Initial energy
Final energy
Initial kinetic energy - Final kinetic energy 
of initial kinetic energy.
After solving, we get,
