[Question]: 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?
[Answer]: 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.
So the answer is 32.

[Question]: Lucy has been trying new recipes and wants to make sure she keeps the cupboard stocked with ingredients. She had a 500g bag of flour in the cupboard at the start of the week. She used 240g when she baked cookies on Tuesday, and accidentally spilled half of what was left when she was putting the flour away. If Lucy wants a full bag of flour in the cupboard, how much flour does she need to buy, in grams?
[Answer]: After baking cookies, Lucy had 500 – 240 = 260g of flour left. She accidentally spilled half of this, which means she had 260 * 0.5 = 130g of flour left. She therefore needs 500 – 130 = 370g of flour.
So the answer is 370.

[Question]: Jacque arrived in France and his suitcase weighed 5 pounds. While in France, he picked up 5 bottles of perfume that weighed 1.2 ounces each, 4 pounds of chocolate, 2 bars of soap that weighed 5 ounces each and 2 jars of jam that weighed 8 ounces each. Considering 16 ounces is the same as 1 pound, how much did Jacque's suitcase weigh on the return flight home?
[Answer]:
He bought 5 bottles of perfume that weighed 1.2 oz each so they weighed 5 * 1.2 = 6 oz. 2 bars of soap weighed 5 oz each so they weighed 2 * 5 = 10 oz. 2 jars of jam weighed 8 oz each so they weighed 2 * 8 = 16 oz. The perfume is 6 oz, the soap is 10 oz and the jam is 16 oz for a total of 6 + 10 + 16 = 32 oz. 16 oz is 1 pound, and he had 32 oz in products so he had 32 / 16 = 2 pounds of products. His suitcase weighed 5 pounds, and the chocolate weighed 4 pounds and the remaining products weighed 2 pounds so his suitcase weighed 5 + 4 + 2 = 11 pounds.
So the answer is 11.
