[Question]If two piles of toys added together make 120 toys in total, and the larger of the two piles is twice as big as the smaller one, how many toys are in the larger pile?
[Answer]First, we set up the equation 3x = 120, dividing both sides by three to find that x = 40. Then we multiply X by 2 to find that 40 * 2 = 80. As 80 / 2 = 40, and 40 + 80 = 120, we find the sizes of the two piles as the larger pile is twice as big as the smaller pile, confirming that 80 is the answer. The answer is 80.

[Question]Dexter filled 3 fewer plastic boxes with football cards than basketball cards. He filled 9 boxes with basketball cards and each box has 15 cards. For the boxes with football cards, he filled each box with 20 cards. How many cards does Dexter have in total?
[Answer]Dexter have 9 x 15 = 135 basketball cards. He filled 9 - 3 = 6 plastic boxes with football cards. So, he has 6 x 20 = 120 football cards. Therefore, Dexter has 135 + 120 = 255 cards in total. The answer is 255.

[Question]In a town, there are four primary schools. Two of them can teach 400 students at a time, and the other two 340 students at a time. How many students at a time in total, can these four primary schools teach?
[Answer]Two schools can teach 400 students, so in total, they can teach 2 * 400 = 800 students. The other two schools can teach 340 students, which gives 2 * 340 = 680 students in total. So all four schools can teach 800 + 680 = 1480 students at a time. The answer is 1480.

[Question]A high school bowling team's 3 members scored a total of 810 points in their first match. The first bowler scored 1/3 as many points as the second, and the second bowler scored 3 times as high as the third bowler. How many points did the third bowler score?

Let x represent the score of the third bowler. Bowler 2:3x. Bowler 1:3x(1 / 3) = x. Total:x + 3x + x = 810. 5x = 810. x = 162 points. The answer is 162.
