You can put this solution on YOUR website! .
Hello, I do not understand Hindi, too.
But you actually DO NOT NEED know Hindi, because later he writes EQUATIONS.
Equations are UNIVERSAL language of Math and Physics.
One equation says that the net horizontal force is equal to zero, providing
equilibrium in horizontal direction.
Another equation says that vertical projections of the ropes tensions sum up to total weight 400 N + 120 N = 520 N,
providing equilibrium in vertical direction.
That is all.
