Q.1 The maximum % increase in price of share on Day 2 compared to Day 1 at exactly the same time on the two days was at:-
We have to look at the increase on Day 2 when compared to same time on day 1. So, at 0900h on day2 over 0900h on day 1.
Scan the graph for the maximum gap between two lines where yellow line is the lower line.
Two such points are at 1000h and 1500h. But we are looking at maximum % increase, so look which point has lower value on day 1 as that will be the reference point on which increase is made.
increase of 50 on 10 would give higher % than increase of 50 on 20. Hence, 1000h is the answer.
Q.2. For each of the following statements, select Supported if, according to the information provided, the statement is true. Otherwise select Not Supported.
(a) The ATS A gives a profit on each day.
The ATS A buys shares at 0900h and sells half of it at 1200h and 1500h, so they are sold at an average of the prices at these two times.
Day 1: Buy - 120; sell - (120+140)/2 or 130...Hence profit of $10 per share
Day 2: Buy - 130; sell - (120+160)/2 or 140...Hence profit of $10 per share
Supported
(b) The profit per share on both the days by either of the ATS giving profit is the same.
ATS A gives profit on each day and is equal to $10 on each day. Hence, supported.
(c) The range of the price per share is more on Day 1.
The lower point of each line is at 110 but the higher point on Day 2 id 10 more than tha on day 1. Hence, the range will be higher on Day 2.
Not supported
Q.3. For each of the following statements, select Yes if the question can be answered based on the information in the passage. Otherwise, select No.
(a) On which day did ATS A give more profit for each share sold?
ATS A gave the same profit of $10 per share. So, YES
(b) What is the total loss incurred by ATS B over the two days?
We do not know the exact number of shares purchased by the ATSs, so NO.
(c) If there were equal shares traded at 0900h on each day by ATS A and ATS B, what was the combined profit/loss over two days.
The activity done by A and B is opposite of each other at exactly the same time and for same amount, so the overall profit will be Zero...YES
in Q3 - Part 1, shouldn't the option be "No", since, ATS A generates equal profit per share ($10)? Hence, we can't confirm which day gave more profit.
I was thinking along the above logic, thus opted for "No".
Please suggest gaps in my understanding.
Thanks for the series. Extremely helpful.
Cheers!
