two numbers are in respectively 20 % and 50 % more than a third number . the ratio of the two numbers is ?
"let the 3 rd number be x then , first number = 120 % of x = 120 x / 100 = 6 x / 5 second number = 150 % of x = 150 x / 100 = 3 x / 2 ratio of first two numbers = 6 x / 5 : 3 x / 2 = 12 x : 15 x = 4 : 5 answer is c"
divide(add(const_100, 20), add(const_100, 50))
