two numbers are respectively 20 % and 50 % more than a third number . the ratio of the two numbers is
"explanation : let the third number be x . first number ( 120 / 100 ) * x = 6 x / 5 second number ( 150 / 100 ) * x = 3 x / 2 ratio = 6 x / 5 : 3 x / 2 = > 4 : 5 option c"
subtract(const_100, multiply(divide(add(20, const_100), add(50, const_100)), const_100))
