X=125

Y=150

Y>X

Y will be greater than X by mere observation because 14% percentage of it has a value not very much less than a double percentage of X

Step-by-step explanation:

28%X = 35

100%X = (100x35) / 28 = 125

14%Y = 21

100%Y = (100x21) / 14 = 150

Y is greater than X

Y will be greater than X by mere observation because 14% percentage of it has a value not very much less than a double percentage of X
