"say a 100 families existed in 1998 then the number of families owning a computer in 1998 - 20 number of families owning computer in 2002 = 20 * 140 / 100 = 28 number of families in 2002 = 108 the percentage = 28 / 108 * 100 = 25.92 % . answer : e"
multiply(const_100, divide(divide(multiply(add(40, const_100), 20), const_100), add(const_100, 8)))
