1) The price of 2 doughnuts was $0.10 less than the price of 3 cupcakes. 2) The average price of 1 doughnut and 1 cupcake was$0.35.

E. From i and ii: price of a doughnut = 0.40 and price of a cupcake = 0.30

nd + mp = 6
n = number of doughnuts
m = number of cupcack

1: 3p - 2d = 0.1 .............i
2: p + d = 2 (0.35) .....................ii

From i and ii: d = 0.40 and p = 0.30

If n = 0, m = 15.
If n = 4, m = 12.
....................
....................
If n = 20, m = 0

E..

Hi GMAT TIGER ,

Thanks for the explanation. I understood your calculation and logic behind 'E'.

However, I also came to the same conclusion. But for diffrent reasons. Please help me to understand whether I am wrong.

I assumed that there could be a burgain price for buying more than 1 of either of the items. So, when I buy one Doughnut or 1 Cupcake, the price charged could be more than a burgain price.

Thus, from both statements together I won't be able to answer the Q.

My Q to you is "Is my assumtion valid?" ---> For this Q or any similar Q?

Nope. You cannot go beyond the question and info provided. Your assumption do not have any effect on the answer because the answer is E. If it were other than E, your assumption would have altered the answer. In that case, you would be trapped to wrong answer. Your answer must be based only on the info provided..
