Question: There were 30 women and 20 men who attended the party. After few hours, 2/5 of the total number of people left. If 9 men left the party, how many more women stayed at the party than men?
Answer: There were 30 + 20 = 50 attendees at the party. A total of 50 x 2 / 5 = 20 people left the party. Nine of those who left were men while 20 - 9 = 11 of them were women. So, 30 - 11 = 19 women stayed at the party. And 20 - 9 = 11 men stayed at the party. Thus, 19 - 11 = 8 more women than men stayed at the party. The answer is 8.
[Question]Patricia is making a highlight film about her basketball team. She recorded video of every player and plans to put it all together in a longer movie. She has 130 seconds of the point guard, 145 seconds of the shooting guard, 85 seconds of the small forward, 60 seconds of the power forward, and 180 seconds of the center. How on average, how many minutes does each player get?
[Answer]The total movie is 600 seconds long because 130 + 145 + 85 + 60 + 180 = 600. The total movie is 10 minutes long because 600 / 60 = 10. On average each player gets 2 minutes because 10 / 5 = 2. The answer is 2.
Q: Mrs. Thomson received an incentive worth $240. She spent 1/3 of the money on food and 1/5 of it on clothes. Then, she put in her savings account 3/4 of the remaining money. How much money did Mrs. Thomson save?
A: Mrs. Thomson spent $240 x 1 / 3 = $80 on food. She spent $240 x 1 / 5 = $48 on clothes. So she spent a total of $80 + $48 = $128 on food and clothes. Hence, she had $240 - $128 = $112 left after buying food and clothes. Then, Mrs. Thomson saved $112 x 3 / 4 = $84. The answer is 84.
Question: In a Zoo, there are different animals. There are 5 giraffes and twice as many penguins. Penguins make up 20% of all the animals in the Zoo. How many elephants are there in the Zoo if they make up 4% of all the animals?
Answer: There are twice as many penguins as giraffes, so there are 5 * 2 = 10 penguins. The penguins make up 20% of all animals, so there are 100 / 20 * 10 = 50 animals in the whole Zoo. 4% of animals are elephants, so there are 4 / 100 * 50 = 2 elephants at the Zoo. The answer is 2.
[Question]A 26-mile circular marathon has four checkpoints inside it. The first is one mile from the start line, and the last checkpoint is one mile from the finish line. The checkpoints have equal spacing between them. How many miles apart are each of the consecutive checkpoints between the start-finish line?
[Answer]The checkpoints are 1 mile from the start and finish, so they are spaced along 26 - 1 - 1 = 24 miles. There are 4 equally spaced checkpoints, so the checkpoints are 24 / 4 = 6 miles apart. The answer is 6.
