S1. k=0.2n
We have a relation betwen k and n, so we can easily take out n is what percent of k.

Sufficient!

S2. (k+n)/n=1.2

(k+n)/n = 1.2 ---> k/n + 1=1.2 ---> k/n=0.2

Same as S1.

Sufficient!

Hence, answer is D.

==> If you modify the original condition and the question, from n=(some)(1/100)k, you get some=100(n/k). However, con 1) = con 2), so you get some=100(0.2)=20, hence it is unique and sufficient.

Therefore, the answer is D.
Answer: D

1) \(k = 0.2n\)
\(n = 5k = \frac{500}{100} k\)
\(n\) is 500% of \(k\)

2) \(\frac{k+n}{n} = \frac{6}{5}\)
\(5k + 5n = 6n\)
\(n = 5k = \frac{500}{100} k\)
\(n\) is 500% of \(k\)

Happy Studying !!!
