Answers:

1. As per the order of operations, those inside the parentheses are to be calculated first. That’s how you get this: 6 ÷ 2×3 = 9.

 

2. #3.

 

3. The boys have 12 chocolates all in all.

 

4. Based on Archimedes’ Principle, the weight of the submerged piece of ice is the same as the weight of the fluid displaced by the ice. At first, the level of the water was lowered. But when the ice melted, it turned into water of the same weight. So, the water level won’t change.

 

5. For you to solve this puzzle, all you need to do is "turn back" time. First, 1 hour and 10 minutes back, then 1 hour and 20 minutes, and finally 1 hour and 30 minutes. That is why if you do the same to clock #4, you’ll get the time that clock #5 shows: 5:35.

 

 

 

6. The correct pattern is: 7 — 3 = 4, 7 + 3 = 10, 7 * 3 = 21. If you put the answers together, you’ll get 41021.

 

7. Objects that are submerged in water each has an apparent weight loss that is the same with the weight of the displaced fluid. The stone takes up more space than the iron balance weight. So, the stone will displace more water and thus will become lighter. That will tilt the balance.

 

8. One of them has to have an apple with the basket.

 

9. The following are the correct symbols:

 

 

10. Actually, there are 10 numbers in this picture:
