the tax on a commodity is diminished by 25 % but its consumption is increased by 10 % . find the decrease percent in the revenue derived from it ?
"explanation : 100 * 100 = 10000 75 * 110 = 8250 10000 - - - - - - - 1750 100 - - - - - - - ? = 17.5 % e )"
subtract(const_100, divide(multiply(add(const_100, 10), subtract(const_100, 25)), const_100))
