Ok now I'm not soo sure anymore......I was pretty sure I got it wrong. Unfortunately, I didn't save that test so I can't go back and check.

I'll try to re-take the test, hopefully the question will come up again.

Thanks

Can you please post correct answer when you find it. I am for E as well. Not enough data to determine p

Ok so here is my answer ..

From the question stem we have that Karen's and Jason's salary in 98 is (1+p/100) times greater than that in 95 ..

Let the salary of Karen and Jason be x and y in 95, so in 98 it will be x(1+p/100) and y(1+p/100) respectively.

From the first statement we have x- y =2000, we have 1 equation and 2 unknowns, so not sufficient.

From the second statement we have x(1+p/100)-y(1+p/100) = 2440, again we have 1 equation and 3 unknowns, so this statement by itself is again insufficient..

Now, from the second statement we have (x-y) (1+p/100) = 2440, but we also know that x-y =2000, so 1+p/100 = 2440/2000 = 1.22, so p =22% .. So the answer is C .. sorry for the confusion created by the earlier post ..

Neat explantion ...now its clear ..C it is ..
