The 2nd statement says Kalley started with two times as much money as Lisa, the keyword here is started with. Now they may have started with 2x and x amounts respectively but they might invest more money during the course of 2 years in question.

So even taking (1) & (2) statements together doesn't answer the question.

Correct Ans: E

I am not sure if we are supposed to consider outside information or assumptions such as

but they might invest more money during the course of 2 years in question when solving DS questions.

With the given constraints and without considering the highlighted assumption, wouldn't the answer be C?

Kelly = 2x and made 5%

Lisa = x and made 20%

Even if Kelly made zero profit and stayed at 2x, in order for Lisa to catch up with Kelly, she has to make at least 100% on her investment. So, Kelly made more money. Answer C.

It is not an assumption but a possible condition. In DS questions we are required to evaluate all the possible conditions. For e.g. even if a statement is true for all integers, we still have to evaluate for fractions. Now coming back to this question, since the question asks

Over the last two years who made more investing in stock market Lisa or Kalley. so it is not enough to just consider the investments made at the beginning of the 2 years period. We have to consider the case if investments were made during the 2 years period.

In DS we have to be 100% sure that the statements provide enough information to answer the question. There cannot be an iota of doubt.
