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 ?

Let J = 100.
125% of J = 125.

Since 125 is 25%=1/4 of K, K = 4*125 = 500.

150% of K = 750.
Since 750 is 50%=1/2 of L, L = 2*750 = 1500.

175% of L = 1.75*1500 = 2625.
Since 2625 is 75%=3/4 of M, M = (4/3)*2625 = 3500.

20% of M = .2*3500 = 700.
200% of J = 2*100 = 200.
(700/200)*100 = 350%.

The correct answer is D.
