Q: 4 students participated in a 200m race. If the average completion time of the last three students was 35 seconds, and the average completion time of all four runners was 30 seconds, how long (in seconds) did it take the student who came first to finish the race?
A: The last 3 students had an average completion time of 35 seconds so the sum of their completion times was 3 * 35 = 105 seconds. All 4 students (now including the student who came first) had an average completion time of 30 seconds, meaning the sum of their completion times is 4 * 30 = 120 seconds. The student who came first spent 120 - 105 = 15 seconds in the race. The answer is 15.
Question: James buys pistachios for $10 per can. Each can is 5 ounces. He eats 30 ounces of pistachios every 5 days. How much does he spend on pistachios per week?
Answer: The pistachios cost 10 / 5 = $2 per ounce. He eats 30 / 5 = 6 ounces of pistachios a day. So he spends 6 * 2 = $12 per day on pistachios. So he spends 12 * 7 = $84 per week. The answer is 84.
[Question]In my school, the number of students has increased by 20% this year. The number of students this year is 960. How many students were there last year?
[Answer]Let X be the number of students last year. The number of students this year is X + X * 20% = 960. Combining like terms, we get X * 1.2 = 960. Dividing both sides by 1.2, we get X = 800 students. The answer is 800.
Q: John buys 3 dress shirts. They sell for $20 each. He also has to pay 10% tax on everything. How much did he pay in total?
A: The shirts cost 3 * $20 = $60 before tax. The tax cost $60 * .1 = $6. So in total they paid $60 + $6 = $66. The answer is 66.
Question: Mike watches TV for 4 hours every day. On the days he plays video games he plays for half as long as he watches TV. If he plays video games 3 days a week how long does he spend watching TV and playing video games?
Answer:
He plays video games for 4 / 2 = 2 hours a day. He watches TV for 4 * 7 = 28 hours a week. He plays video games for 3 * 2 = 6 hours. So in total he spends 6 + 28 = 34 hours on those activities. The answer is 34.
