Show Answer

Answer:

Correct Answer: A

Solution:

I. $ {{(625)}^{1/4}}x+\sqrt{1225}=155 $

$ \Rightarrow $ $ {{[{{(5)}^{4}}]}^{1/4}}x+35=155 $

$ \Rightarrow $ $ 5x=155-35 $ $ 5x=120 $
$ \Rightarrow $ $ x=24 $ II. $ \sqrt{196}y+13=279 $

$ \Rightarrow $ $ 14y=279-13 $

$ \Rightarrow $ $ 14y=266 $
$ \Rightarrow $ $ y=19 $

$ \therefore $ $ x>y $
