Q: A clothing store has an inventory of 34 ties, 40 belts, 63 black shirts, and 42 white shirts. The number of jeans in the store is two-thirds of the sum of black and white shirts, and the number of scarves is half the number of the sum of ties and belts. How many more jeans are there than scarves?
A: The sum of black and white shirts is 63 + 42 = 105. The number of jeans in the store is (2 / 3) x 105 = 70. The sum of ties and belts is 34 + 40 = 74. The number of scarfs in the store is 74 / 2 = 37. There are 70 - 37 = 33 more jeans than scarfs in the store. The answer is 33.

Q: Johan has a ten-bedroom house with 8 walls in each room. He paints 3/5 of the rooms in the house green and paints the rest of the rooms with purple color. How many walls in the house did he paint purple?
A: Since Cristian's house has ten rooms, he painted 3 / 5 * 10 = 6 rooms with green color. The number of rooms he painted with purple is 10 - 6 = 4 rooms. Since each room in the house has eight walls, the number of walls painted purple is 8 * 4 = 32. The answer is 32.
