m is 30 % of q . q is 20 % of p . n is 50 % of p . find m : n ratio
let p be 100 n = 50 % of 100 ( p = 100 ) = 50 q = 20 % of 100 ( p = 100 ) = 20 m = 30 % of 20 ( q = 20 ) = 6 m : n = 6 : 50 m : n = 3 : 25 answer : c
divide(multiply(divide(30, const_100), divide(20, const_100)), divide(50, const_100))
