Statement (1)
1. r - s=2s and(t - 2s)^2 = 0
r=3s we can find r/s from this
(t-2s) (t-2s) = 0 => t-2s = 0 i.e t=2s we can get the ratio s/t from this
With r/s ratio and s/t we can find r:s:t
SUFFICIENT
Staement (2) INSUFF Just gives value of r and t
No info & provides no way to find a ratio between r,s and t
A)

Davy,
I am sure you would get problems right too; its just a matter of time. Making mistakes is good in the learning process i.e next time we wont.
I used to make mistakes all the time too (by overlooking facts & not considering all possible values to determine sufficiency etc..) Even now I do. its all in the game(part of learning)
If u read through some of DS posts here u will learn a lot.(i.e how one approaches the problem; different value ranges to be considered for different problems etc)
Practice OG probs and try to read through the explanation and if u still have doubts post it here. There are so many experts / users(like me not an expert for sure) on this site and your question will be answered.
Let me know if u have any more questions. Good luck! You will do good!
