[For Seniors] Fun Brain Training! A Collection of Tricky Quizzes You’ll Definitely Get Stumped By (1–10)
We split 200 candies in half and added 5 candies. How many candies are there now?
See the answer
7 pieces
If you read the question carefully, it becomes easier to arrive at the answer. If you think of “dividing 200 in half,” you get 100, but the problem asks you to “divide 200 by half.” If you divide 200 by half (that is, by 0.5), you get 400, right? Then you add 5, so the answer is 405. Just a one-character difference can lead to a completely different number!
A driver of a large truck is driving on a road where large vehicles are prohibited. However, a nearby police officer neither warns nor arrests him. Why is that?

Because the driver of a large truck was speeding
If a large truck is driving on a road where large vehicles are prohibited, that’s a problem. However, if it’s the driver of the large truck who is running, there’s no problem, right? From the feel of the question, it seems the key is that it makes you picture a large truck.
To drink tea, I boiled water in a kettle. Four hours later, when I tried to have tea, there was no water left in the kettle. Why is that?
See the answer
Because the hot water cooled down and turned into water.
It’s a problem that makes sense once you know the answer, isn’t it? You might be tempted to think about why the hot water disappeared from the kettle, but the key point is the time—“four hours.” As time passes, if the water isn’t being heated, it will cool down. The hot water in the kettle turned back into regular water, making it seem like the hot water was gone.
There were ten pheasants in the mountains. A hunter shot one with a gun—how many pheasants are left?
See the answer
0 birds
If you work through the numbers in the problem, there are 10 pheasants, one is shot, and 9 remain. But in everyday life, what would happen if a loud noise like a gunshot went off near the pheasants? They would be startled by the loud sound and fly away. That’s the kind of answer you get with a trick question!
A certain family was eating at a restaurant. A child sitting with the family knocked over a cup that was on the table, but the table didn’t get wet. Why is that?
See the answer
Because the cup was empty
It often happens that small children accidentally push a cup with their elbow during a meal and knock it over. Some of you may recall the scene of a table wet with spilled drinks. Fortunately, it seems the cup didn’t have any beverage in it this time.
Sandwiches, croquettes, grilled chicken skewers, and apples at the supermarket. Which of these was the first to get sold?
See the answer
Apple
This is a puzzle where the keywords are “ureta,” “売れた” (sold), and “熟れた” (ripe). Although the puzzle mentions “ureta,” the correct answer isn’t “sold” but the food that is “ripe.” Since “熟れた” is used for fruits and grains, the correct answer is an apple.
Taro went to the candy shop with 400 yen he received from his mother. If he buys candy for 300 yen, how much change will he get?
See the answer
0 yen
It might seem like the change would be 100 yen, but let’s think about it a bit! You bring 400 yen and buy 300 yen worth of candy at a sweets shop—but how do you pay? Unlike a 500-yen coin, the 400 yen you brought consists of small coins like 100-yen and 10-yen coins. If you pay exactly 300 yen in small coins, you won’t receive any change. It’s an interesting problem that can be misleading if you try to picture the situation described in the question.
