Problem: if 50 % of x is 25 less than 25 % of 2500 , then x is ?
Rationale: "50 % of x = x / 2 ; 25 % of 2500 = 25 / 100 * 2500 = 625 given that , x / 2 = 625 - 25 = > x / 2 = 600 = > x = 1200 . answer : c"
annotated_formula: divide(subtract(multiply(2500, divide(25, const_100)), 25), divide(50, const_100))
