E it is.

n = (m)*(10/100)*(25/100)
n = (m)*(1/10)*(1/4)
n = m/40

Therefore, 40n = m (cross-multiplication). If m is 40 times n, that means m is 4000% of n.

You can also solve this by using numbers;
Lets say m = 200
from the problem statement we know that n is 25% of 10% of 200. Thus, n=5

Now, we need to find out 200 is what percent of 5.
In other words, 200 = 5*(x/100). As a result, we get x = 4000.

Hope that helps.
