It's almost midnight, I am about to finish my studies for the day (yup, from morning till now) and this is the problem I get:

**If 125% of j is equal to 25% of k, 150% of k is equal to 50% of l, and 175% of l is equal to 75% of m, then 20% of m is equal to what percent of 200% of j ?**
It's got to be a cruel joke, I have no idea how to tackle this, unless I substitute some numbers here and do the arduous work of calculating everything. But there must be a faster way. Will you please help? Last one for today, I promise.
