the difference of two numbers is 20 % of the larger number . if the smaller number is 12 , the larger one is :
"let the larger number be x . then , x - 12 = 20 % of x < > x - ( x / 5 ) = 12 4 x / 5 = 12 < = > x = ( 12 ∗ 5 ) / 5 = 15 . answer : a"
add(subtract(multiply(divide(const_10, const_2), 12), divide(add(20, multiply(divide(const_10, const_2), 12)), const_2)), divide(const_10, const_2))
