This is the only question I'm answering on this thread, henceforth please email me! I'm just lazy to come here everyday : P

The resultant force acting on the whole system = F
Newton's 2nd law: F= mass x acceleration

Since the blocks are joined, they move with the same acceleration. but their total mass is 4m.

so: F=4ma ---->first equation

The question asks for the force exerted by block X on block Y, this is the same (i.e equal magnitude but opposite in direction) as the reaction by block Y on block X.

mass of block Y=3m

let the force exerted by X on Y = force exerted by Y on X =F1



F1= 3ma ----->second equation

from the first equation, we see that:
ma = F/4

replacing this in the second equation:


F1= 3 x (F/4) = 3F/4

Practice, practice, practice. That's really all there is to it. Keep trying, eventually it will come naturally to you. Work out every single paper, every question you can get your hands on. If you have to spend two hours on a single question to get the right answer, do it. This will help you enormously for your exams later on.

Good luck and best wishes! :)
