finally after a long workout did manage to solve the problem
here is the solution
consider the height of the tower to be h
so the first ball will take t seconds to cover the distance of(h-55) m  and the second ball will take t+ 2 seconds to cover the same distance in that 2 seconds the first ball will cover 110m
so in the case of the first ball we have two types of motions upward and downward it will cover both the types of motions in equal time intervals so we get the initial velocity which is the final velocity for the distance of (h-55) with which we get the distance of h-55 finally we get the awnser as180m
this is onemethod ialso manged tofigure out another one but it is slightly complicated
