a sells a cricket bat to b at a profit of 20 %. b sells it to c at a profit of 25 %. if c pays $ 225 for it, the cost price of the cricket bat for a is:
divide(225, multiply(add(const_1, divide(20, const_100)), add(const_1, divide(25, const_100))))
"a 150 125 % of 120 % of a = 225 125 / 100 * 120 / 100 * a = 225 a = 225 * 2 / 3 = 150 ."
