variation
posted by cynthia
the load which a crame can lift up is directly proportional to the mass and inversely proportional to the height through which the load is to be lifted.if a load of 40 and mass of 175gm is lifted through height of 286m,from what load will be carried through height 50m given the mass as 250gm?

"variation" is not your school subject. This looks like physics. For all I knew, you could have been asking about the variation of terrain in the Sierra foothills or the variables in a public opinion survey  anything.

Finally! Your variation description says that
L = km/h
so, Lh/m = k is constant. So, you want L such that
L*50/250 = 40*286/75
