[Question]: Hugo can fold a small box in 3 seconds and a medium one in twice that time. Tom can fold both the small and medium boxes in 4 seconds. If Hugo and Tom want to leave as early as possible, how long (in seconds) will it take them to fold 2400 small boxes and 1800 medium boxes?
[Answer]: If it takes Hugo twice the amount of time to fold a medium box than a small box, then he needs 2 * 3 = 6 seconds for the medium box. If Tom can fold either the small or medium box in 4 seconds, then he's faster at folding the medium box than Hugo because 4s < 6s. If Hugo can fold the small box in 3 seconds, then he's faster at folding the small boxes than Tom because 3s < 4s. Therefore Hugo should fold all small boxes and Tom should fold all the medium ones before doing the other size where they are slower. If there are 2400 small boxes and Hugo can fold 1 box in 3 seconds, then it would take him 2400 * 3 = 7200 seconds to fold all boxes. If there are 1800 medium boxes and Tom can fold 1 box in 4 seconds, then it would take him 1800 * 4 = 7200 seconds to fold all medium boxes. Given that they need the same amount of time to fold all boxes, and are doing it simultaneously they will need 7200 seconds to fold all the boxes.
So the answer is 7200.

[Question]: If a basket is capable of holding 40 fruit altogether, and there are 3 times as many apples as oranges, how many oranges are there?
[Answer]: Since the ratio of apples to oranges is 3:1, that means for every 3 apples there is 1 orange. The size of this group is therefore 3 + 1 = 4. We then divide this group size into the total amount of fruit the basket is holding at this time, which is 40. This means there are 40 / 4 = 10 of these groups in total. Since there are 10 of these groups in total, that means there are 10 * 1 = 10 oranges in the basket.
So the answer is 10.

[Question]: A factory manufactures cars with 5 doors. The factory was planning to produce 200 cars but due to metal shortages, they decreased the production by 50 cars. Due to a pandemic, they also had to cut production by another 50%. How many doors will the factory produce?
[Answer]:
The factory due to shortages will produce 200 - 50 = 150 cars. Due to the pandemic, they will now produce 150 / 2 = 75 cars. The company will have to manufacture 75 * 5 = 375 doors.
So the answer is 375.
