the cost price of 24 articles is the same as the selling price of x articles . if the profit is 20 % , what is x ?
"let the cost price = y the cost price of 24 articles = 24 y the selling price of x articles = 1.20 y * x 1.20 y * x = 24 y x = 24 / 1.2 = 20 the answer is d ."
divide(multiply(24, const_4), add(const_4, const_1))
