I got this on the MGMAT CAT yesterday, and I don't understand how this can be classified as a 700-800 level question. There is no way someone could solve this problem in under 2 minutes. This has got to be a 900+ level question:
An investor purchased a share of non-dividend-paying stock for p dollars on Monday. For a certain number of days, the value of the share increased by r percent per day. After this period of constant increase, the value of the share decreased the next day by q dollars and the investor decided to sell the share at the end of that day for v dollars, which was the value of the share at that time. How many working days after the investor bought the share was the share sold, if r=100(sq rt. [V+Q/P] -1) ?
A) Two working days later.
B) Three working days later.
C) Four working days later.
D) Five working days later.
E) Six working days later.
