[Question]Merill has twice as many marbles as Elliot and the two of them together have five fewer marbles than Selma. If Selma has fifty marbles, how many marbles does Merill have?
[Answer]If Selma has fifty marbles, then Merill and Elliot together have 50 - 5 = 45 marbles. We'll assume the number of marbles that Elliot has is x. If Merill has twice as many marbles as Elliot, then the total number of marbles that Merill and Elliot have together is 2x + x = 45 marbles. This translates to 3x = 45. The number of marbles that Elliot has is x = 45 / 3. This means Elliot has x = 15 marbles. Since Merill has twice as many marbles as Elliot, Merill has 2 * 15 = 30 marbles. The answer is 30.
Q: In a conference room, 40 chairs with a capacity of 2 people each were arranged in rows in preparation for the board meeting of a company, whose number of members was the same as the chairs' capacity. If 2/5 of the chairs were not occupied, and the rest each had two people, calculate the number of board members who did attend the meeting.
A: The total capacity of the 40 chairs was 40 * 2 = 80 people. If 2 / 5 of the chairs were unoccupied, 2 / 5 * 80 = 32 people missed the board meeting since the number of members was the same as the chair's capacity. The number of board members who attended the meeting was 80 - 32 = 48. The answer is 48.
Question: Sam shared a sum of money between his three cousins Sandra, Amy and Ruth in the ratio 2:1:3 respectively. If Amy got $50, how much did Sandra get?
Answer: Going by the ratio, for every 1 part that Amy gets, Sandra will get 2 parts. Since Amy got $50, Sandra will get 2 * $50 = $100. The answer is 100.
[Question]Jill and her brother Jack are going apple picking. Jill's basket can hold twice as much as Jack's basket when both are full. Jack's basket is full when it has 12 apples, but currently space for 4 more. How many times could Jack's current number of apples fit into Jill's basket?
[Answer]Since Jill's basket can hold twice as much as Jack's, and Jack's is capable of holding 12 apples in total, this means Jill's basket can hold 12 * 2 = 24 apples in total. Since Jack has 4 less than the maximum amount of apples he can fit in his basket, this means Jack has 12 - 4 = 8 apples in his basket. Therefore, Jill's basket can hold 24 / 8 = 3 times the amount of apples Jack is currently carrying. The answer is 3.
[Question]Mark has a garden with flowers. He planted plants of three different colors in it. Ten of them are yellow, and there are 80% more of those in purple. There are only 25% as many green flowers as there are yellow and purple flowers. How many flowers does Mark have in his garden?
[Answer]
There are 80 / 100 * 10 = 8 more purple flowers than yellow flowers. So in Mark's garden, there are 10 + 8 = 18 purple flowers. Purple and yellow flowers sum up to 10 + 18 = 28 flowers. That means in Mark's garden there are 25 / 100 * 28 = 7 green flowers. So in total Mark has 28 + 7 = 35 plants in his garden. The answer is 35.
