Explanation

x is 0.5% of y. So if you fix a value of \(y\), any value at all, you fix x.

Lets do that, say y=100.

x= 0.5% of y or \(x=\frac{0.5}{100} \times y\)=0.5

Now y is what percent of x part. This is where it get a bit tricky!

Now \(\frac{y}{x}=\frac{100}{0.5}=200\).

Or y is 200 times x. which is 20000%.

Note percent can be broken down as per - cent. Here per means for every (or divided by) and cent means (100).

So for every 100 of x we have \(100 \times 200\) of y.

this question can we do it like this
x=(0.5/100)*y; 200x=y
we have y=(n/100)*x now if we substitute the value of "y" from the previous equation
200x=(n/100)*x
we get "n" = 20000

is this the right way to approach this question? i feel that x and y can be completely different values so this method wont work. Am i write about this?
