Come up with a question and reasoning that would justify [200] as the answer.
The question is: Arthur knows that he needs to finish 800 pages of reading over the summer. He has read 80% of a 500-page book and 1/5 of a 1000 page book. How many more pages does he need to reach to meet his goal?
Reasoning: He read 400 pages from the 500 page book because 500 x .8 = 400. He read 200 pages from the 1000 page book because 1000 x (1 / 5) = 200. He has read 600 pages in total. He needs to read 200 more pages to reach 800 pages because 800 - 600 = 200.

Come up with a question and reasoning that would justify [120] as the answer.
The question is: Aubrey is planting tomatoes and cucumbers in her garden. For each row of tomato plants, she is planting 2 rows of cucumbers. She has enough room for 15 rows of plants in total. There is enough space for 8 tomato plants in each row. If each plant produces 3 tomatoes, how many tomatoes will she have in total?
Reasoning: Since one out of every 3 rows will contain tomato plants, there will be 15 / 3 = 5 rows of tomato plants. This gives her enough room to plant 5 rows * 8 plants / row = 40 tomato plants. The plants will produce a total of 40 * 3 = 120 tomatoes.

Come up with a question and reasoning that would justify [135] as the answer.
The question is: Nick's cell phone was initially empty but was then charged for 45 minutes and has reached a 25% charge. How much longer must the cell phone be charged to reach 100% charge?
Reasoning: The ratio between the time charged and the time to be charged is 100 / 25 = 4. To reach 100%, the cell must be charged for 45 minutes * 4 = 180 minutes. Subtracting the 45 minutes that Jimmy already used to charge the cell phone, there are still 180 - 45 = 135 minutes of charging time left.
