GRE New regulations go into effect in 2003 that require all planes.jpg [ 55.88 KiB | Viewed 1850 times ]
New regulations go into effect in 2003 that require all planes in inventory to be newer than ten years old. Each year following 2002, both airlines need to sell the planes the regulations force them to eliminate from inventory, and then use the proceeds of those sales to increase their inventory by 10% (rounded down because they are unable to buy fractions of planes). What is the combined number of planes owned by the two companies following their sales and purchases in 2004 ?

You have to calculate how many planes each company sells and buys for 2003 and 2004 in order to calculate the total number of planes in 2004. In 2003, each company sells the planes they bought 10 years prior to 1993. For A: 250 × 10% = 25 planes removed; for B, 450 × 20% = 90 planes removed. In 2003 A has only 225, so they add 10%, or 22 new planes, for a new total of 247, and B has 360 left, so they add 36 for a new total of 396. In 2004, they sell the old planes they bought in 1994: For A, 250 × 4% = 10 planes; for B, 450 × 14% = 63 planes. Now A has 247 − 10 = 237, so they add 23 for a 2004 total of 260. B now has 396 − 63 = 333, so they add 33 for a 2004 total of 366. 260 + 366 = 626 planes in 2004.
