Solution
y = k*x/z^2 where k is a constant
we can write : y1/y2 = (x1/z1^2)z2^2/x2
(y1/y2) = (x1/x2)*(z2/z1)^2
y1 = 33 ; x1 = 75 ; z1=9 ; y2 = ? ; x2 = 48 ; z2 =4
(33/y2) = (75/48)*(4/9)^2
33/y2 = (75*16)/(48*81)
33/y2 = (25/27)*((1/3)
y2 = 33*27*3/25 = 106.92
y = k*x^3/z^2
(y1/y2) = (x1/x2)^3(z2/z1)^2
(22/y2) = (6/14)^3(6/11)^2
y2 = 455.65
