Agree on 1.

However, Qs.2 = B IMO

The sum of (4x+y), (3y+z), and (3z) = 4x+4y+4z = 4(x+y+z) = 4(50) = 200 or am I missing something obvious?

The question says the average of x, y, and z is 50, so x+y+z=3*50 or 150. So it should be 4(150)=600

Average of $$x$$,$$y$$ and $$z$$ is $$50$$ means $$\frac{x+y+z}{3} = 50$$

see the picture

you need to find d = sqrt(x^2 + l^2)
x=sqrt(h^2 + w^2)
= sqrt(3^2 + 4^2) =5
d= sqrt(5^2 + 12^2)
=13
