ANSWER
_____________________________
Maximum friction (f) = μ × N
=> f = 10 N × μ
=> f = (10 μ) N
In equilibrium I.e. block is held stationary against wall
f = mg
=> mg = ( 10 μ ) N
=> Weight = ( 10 μ ) N

how does friction acts in the upward direction and normal acts towards left
Friction is always an opposing force which opposes motion Since the block is trying to move down friction acts upwards
Normal acts left because a horizontal force is applied towards right
ya thnx
