the ratio of two quantities is 4 : 3 . if each of the quantities is decreased by 8 , their ratio changes to 3 : 1 then the smallest number is ?
"let the numbers be 4 x and 3 x then 4 x - 8 / 3 x - 8 = 3 / 1 4 x - 8 = 9 x - 24 5 x = 16 x = 3.2 smallest number = 3 * 3.2 = 9.6 answer is c"
divide(add(4, 8), add(3, 8))
