X percent of y is y percent of X See related link.
x = 4z/5 y = .72z 5x/4 = z By subsitution, we have: .9x = y Thus, x is 10% more than y, and Without Loss of Generality, y is 10% less than x.
'x' percent of 'y' = [ 0.01x times y ] .
x = 10% solution y = 35% solution .1x+.35y=.20*12 x+y=12 y=12-x .1x+.35(12-x)=.20*12 .1x+4.2-.35x=2.4 -.25x=-1.8 .25x=1.8 x=7.2 gallons y=4.8 gallons
x is y plus 25% of y.
