"say a 100 families existed in 1994 then the number of families owning a computer in 1994 - 60 number of families owning computer in 1998 = 60 * 150 / 100 = 90 number of families in 1998 = 103 the percentage = 90 / 103 * 100 = 87.37 % . answer : e"
multiply(const_100, divide(divide(multiply(add(50, const_100), 60), const_100), add(const_100, 3)))
