Great question! Different!

I see the 13:00 and 16:00 - is that on purpose to make it trickier? I assume so.
Should it say "must have purchased" instead of "most likely"?
­
Yes, the timings are different to make sure you read the question correctly and not jump to conclusions!

The reason I say 'most likely' is because the value of $250 is approximate. Test takers are expected to eye ball the values so in reality there could be a slight variation in the total profit of $250. However, that variation is small enough that no other option comes close.­

­We've been told that the day trader makes a profit of $250 after trading 50 stocks of a particular company.
This means that the stock he bought had a change of 250/50 = $5 from 9 AM to 13:00.
So we are looking for a stock that had gone up by $5 in that time frame. Note that the chart goes beyond 13:00.


In this time from 9 to 13:00 the following price changes occurred. Note that we should check all of them to be safe. You do not need a calculator but can quickly note the differences and which one will be equal to 5.

Company A goes 55 -> 65, i.e. a change of +10
Company B goes 20 -> 30, i.e a change of +10
Company C goes 105 -> 110. i.e. a Change of +5 CORRECT
Company D goes 65 -> 50, i.e a change of -15

The Answer is Company C.


In the second part, we've been asked how much the stock has changed by closing time at 16:00. This is a trap in case you look at 13:00 instead of 16:00.
Therefore, at 16:00, Stock C is at $115, i.e. the change is 115-105 = +$10.

­
You need to find the difference in price of Stock A between 16:00 hours to 09:00 hours. That difference is $10.

What someone might miss is that dropdown 2 is asking you to look at 16:00 hours, not 13:00 hours, which is the first part of the question.

for the 2nd drop down, when you say approximate price change you mean from 9.00 am - 16.00 pm and not from when the dealer sold the stock that is from 13.00 pm to 16.00 pm? Bunuel - please brief. I picked +5 considering from 13.00 he sold for 110 and at the end it is 115

A day trader bought 50 shares of one of the companies shown in the graph, at the stock prices (in dollars) indicated in the graph above. He purchased the shares at 9:00, when the market opened, and sold all 50 shares at 13:00.

Select from each drop-down menu the option that creates the most accurate statement, given the information provided.

If the trader made a total profit of $250 on that day, he bought shares of , which at the market close at 16:00 had an overall price change of approximately .

Yes, the second drop-down refers to the overall price change for that company from market open at 9:00 to market close at 16:00.
