helppp

i don't know how to solve it but heres how to check. pretend x=1 and y=2. find the rate and use it in the second one you will probably see it is not equal to 2

x*x*x = x   (number of men * working hours a day * number of days = number of articles)

y*y*y = something

y = (x) *y/x

x*(y/x)*x*(y/x)*x*(y/x) = x*(y/x)*(y/x)*(y/x)

y*y*y = y^3/x^2

This problem quite tricky.
