Samantha's investment portfolio consists of three stocks: an airline, a bank, and a computer company. In the month of February, the price of the airline's stock rose by 10%, that of the bank decreased by 10% and that of the computer company also decreased by 15%, but the overall value of her portfolio increased. If Samantha owns equal amounts of all three stocks, which of the following could be the initial prices of the three stocks in the order airline, bank, and computer company respectively?
Choose the correct choice from the following options:  A) $55, $85, $40  B) $85, $25, $20  C) $65, $55, $90  D) $65, $60, $60  E) $25, $60, $70
Since Samantha owns equal amounts of stocks, the 10% increase alone should set off the 10% and 15%decrease in each of the other two stocks. i.e The stock which increased should have a substantially higher value than the two stocks which decreased. Between B and D, D is obviously the safer bet and is the right answer.   Answer is $85, $25, $20.
