Question: There were 20 fishermen in the lake who had cast their net to catch fish. If they caught 10000 fish in total, and 19 of them caught 400 fish each with their own net, calculate the number of fish the twentieth fisherman caught.
Answer: The 19 fishermen who caught 400 fish each caught 400 * 19 = 7600 fish. If they caught a total of 10000 fish, the twentieth fisherman caught 10000 - 7600 = 2400 fish alone. The answer is 2400.
[Question]Chloe bought chocolate-dipped strawberries at $50 a dozen. She then sold them for $30 for half a dozen during the Mother's Day celebration. How much is Chloe's profit if she sold 50 dozens?
[Answer]If Chloe bought it for $50 per dozen, then half a dozen cost her $50 / 2 = $25. This means that she has $30 - $25 = $5 profit per half a dozen of chocolate - dipped strawberries. If Chloe sold 50 dozens, then she was able to sell 50 / 1 / 2 = 100 half a dozen chocolate - dipped strawberries. Hence, her profit is $5 x 100 = $500. The answer is 500.
Q: A cup of dog food weighs 1/4 of a pound. If Mike has 2 dogs that each eat 6 cups of dog food twice a day how many 20 pound bags of dog food does he need to buy a month?
A: Each dog eats 6 * 2 = 12 cups of food a day. His two dogs eat 12 * 2 = 24 cups a day. Thus they eat 24 / 4 = 6 pounds a day. So they eat 6 * 30 = 180 pounds a month. So he needs to buy 180 / 20 = 9 bags of food. The answer is 9.
Question: Timmy plans to ride a skateboard ramp that is 50 feet high. He knows he needs to go 40 mph at the start to make it all the way to the top. He measures his speed on three trial runs and goes 36, 34, and 38 mph. How much faster does he have to go than his average speed to make it up the ramp?
Answer: His total speed from the trials is 108 because 36 + 34 + 38 = 108. His average speed was 36 mph because 108 / 3 = 36. He needs to go 4 mph faster to make it to the top because 40 - 36 = 4. The answer is 4.
[Question]Sid takes $48 with him on a shopping trip to the mall. He spent some of his money on computer accessories and another $8 on snacks. After these purchases, he only has $4 more than half of his original money left. How much did he spend on computer accessories?
[Answer]Half of Sid's original money is $48 / 2 = $24. Sid has only $24 + $4 = $28 left after his purchases. He had $28 + $8 = $36 before he spent $8 on snacks. So, Sid spent $48 - $36 = $12 on computer accessories. The answer is 12.
[Question]James can make a beret from 3 spools of yarn. If he has 12 spools of red yarn, 15 spools of black yarn, and 6 spools of blue yarn, how many berets can he make?
[Answer]
First find the total number of spools of yarn James has: 12 spools + 15 spools + 6 spools = 33 spools. Then divide that number by the number spools each beret needs: 33 spools / 3 spools / beret = 11 berets. The answer is 11.
