[Question]Brianna started out with a bag of 24 marbles. She lost four marbles through a hole in the bag. Then, she gave away twice as many marbles as she had lost through the hole in the bag. Finally, her dog ate half as many marbles as Brianna had lost through the hole in the bag. How many marbles did Brianna have remaining?
[Answer]Brianna gave away twice as many marbles as she had lost, or a total of 2 * 4 = 8 marbles. Her dog ate half as many marbles as Brianna had lost through the hole in the bag, or 4 / 2 = 2 marbles. If she started with 24 marbles, then the number of marbles remaining is 24 - 4 - 8 - 2 = 10 marbles. The answer is 10.
Q: Mike is building a bridge out of LEGO blocks. To be successful he needs at least 40 bricks of type A, and half that many of type B. In total, he needs to use 150 bricks. How many bricks of other types than mentioned is he going to use?
A: Mike is using 40 blocks / 2 = 20 blocks of type B. He uses in total 40 blocks + 20 blocks = 60 blocks of type A and B. So he is going to use 150 blocks - 60 blocks = 90 blocks of other types. The answer is 90.
Question: Mr. Maxwell takes 1 hr to drive to work in the morning but 1 and half hours to drive back home in the evening. If the morning and evening traffic is similar and he drives at an average speed of 30mph in the morning, what is the average speed of his return journey?
Answer: In the morning he travels at an average speed of 30mph for 1 hour so he covers a distance of 30 * 1 = 30 miles. He covers the same distance of 30 miles in the evening spending 1.5 hours so his average speed must be 30 / 1.5 = 20mph. The answer is 20.
[Question]In a section of the forest, there are 100 weasels and 50 rabbits. Three foxes invade this region and hunt the rodents. Each fox catches an average of 4 weasels and 2 rabbits per week. How many rabbits and weasels will be left after 3 weeks?
[Answer]3 foxes catch 4 weasels each every week for a total of 3 * 4 = 12 weasels. 12 weasels are caught every week for 3 weeks for a total of 12 * 3 = 36 weasels. 3 foxes catch 2 rabbits each every week for a total of 3 * 2 = 6 rabbits. 6 rabbits are caught every week for 3 weeks for a total of 6 * 3 = 18 rabbits. There were originally 100 weasels so now there are 100 - 36 = 64 weasels left. There were originally 50 rabbits so now there are 50 - 18 = 32 rabbits left. There are 64 + 32 = 96 weasels and rabbits left. The answer is 96.
