two numbers are in the ratio of 5 : 7 . if 20 is subtracted from each number , they are in the ratio of 5 : 9 . what are the two numbers ?
"( 5 x - 20 ) : ( 7 x - 20 ) = 5 y : 9 y 5 x - 20 = 5 y 7 x - 20 = 9 y 140 - 100 = 45 y - 35 y 40 = 10 y y = 4 5 x - 20 = 20 x = 8 the two numbers are 5 x and 7 x which are 40 and 56 . the answer is b ."
subtract(multiply(multiply(subtract(multiply(9, const_4.0), multiply(5, 20)), const_2.0), divide(const_3.0, 5)), multiply(subtract(multiply(9, 20), multiply(5, 20)), 5))
