Problem: 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 $ 237 for it , the cost price of the cricket bat for a is :
Rationale: "125 % of 120 % of a = 237 125 / 100 * 120 / 100 * a = 237 a = 237 * 2 / 3 = 158 . answer c"
annotated_formula: divide(237, multiply(add(const_1, divide(20, const_100)), add(const_1, divide(25, const_100))))
