Opt A)
Given:
poodles - x
dioxins -2/3(x)

2/3(x)+x = 100
5/3(x) = 100
5x = 300
x = 60

Opt - A)

we have d + p = 100

from S2 we get p - d = 20 ( not d-p =20 )

from this we can get d why is S2 not sufficient by itself

Think the OA is wrong. Statement 2 is also sufficient.

Correct answer should be D

Statement II states that the DIFFERENCE between the poodles and the doxin is 20...

In this case, shouldnt there be 2 possibilities?
Case 1: 60 poodles 40 doxin
Case 2: 40 poodles 60 doxin

difference either way is 20....Im taking this question to mean absolute difference..

Statement II insufficient...Is that right??

Casey--then again,Im a newbie just 2 weeks in to studying...what do I know

Newbie or not, you are absolutely right baker2145. Difference means it could be d - p or p - d, hence you cannot find the exact number.
