Problem: the workforce of company x is 60 % female . the company hired 20 additional male workers , and as a result , the percent of female workers dropped to 50 % . how many employees did the company have after hiring the additional male workers ?
Rationale: "let x be the total worker then 0.6 x = female worker and 0.4 x is male worker then 20 male worker added 06 x / ( 0.4 x + 20 ) = 50 / 100 or 60 x = 50 * ( 0.4 x + 100 ) = 20 x + 5000 or 40 x = 5000 , x = 500 / 4 = 125 total worker = 125 + 20 = 145 a"
annotated_formula: add(divide(multiply(divide(50, const_100), 20), subtract(divide(60, const_100), divide(50, const_100))), 20)
