When you solve these kind of problems by assuming variables as x & y, if you do not have two complete equations of x & y , you will get multiple answers . In this case if we assume all numbers are whole numbers and there are no decimals then xy = 3200 & x/y = 2; from equation x/y = 2 , x = 2y which can be substituted in equation 1 to get 2yy = 3200 and y = 40 => x = 80 . But there is no need to do all this when you already have options.
