Math Puzzles For Grade III (8-9 years)
1. In a meeting, there are four people. If each person shakes hands with the other, how many handshakes will happen?
Answer: 6
Explanation
Make a list of all the handshakes made by each person. There will be three handshakes per person; however, the handshakes made by A to B and B to A are the same. So, after removing such repetitions, the answer is 6 handshakes.
2. Solve the additions
Solve the below questions using the clues given
Answer:
- 3+7+3 =13
- 1+7+3 = 11
- 7+7+3 = 17
- 3+7+3+1 = 14
Explanation
According to the clues given, the sum of two triangles is 6, so each triangle’s value is 3.
The sum of a triangle and a circle is 4, since the triangle’s value is 3, the value of the circle is 1.
Similarly, the value of the square is 7, and the rhombus is 3. So, by adding the values of the shapes, we will get the above answers.
3. On one side of a highway, trees are planted adjacent to each other at an equal distance. If the distance between the first tree and the 150th tree is 660m, then what is the distance between two adjacent trees?
Answer: 4.4m
Explanation
There will be 149 gaps between 150 trees. So, the distance between two adjacent trees would require division of 660 by 149 gaps is 4.4m.
4. Find the missing numbers
Answer: 13
Explanation
To solve such math puzzles, you need to identify if there is a common pattern in all four questions. Try subtraction, multiplication, and addition to find the pattern.
The sum of all the numbers in all the four questions comes up to 30, so the missing number in the last question is 13.
5. Neal, Nithin, and Noel have a set of 9 blocks each that are numbered from 1 to 9.
Each one randomly picks a set of three blocks.
Neal says: The product of all the numbers with me is 63.
Nithin says: The product of all the numbers with me is 48.
Noel says: The sum of all the numbers with me is 16.
Which numbered blocks do each of them have?
Answer:
Neal: 1, 7, 9
Nithin: 2, 4, 6
Noel: 3, 5, 8
Explanation
Neal says the product of all the numbers with him is 63 and 1*7*9 is the only possible combination. Nithin might be having numbers 2, 3, 8 or 2, 4, 6, as both give the product 48. But, if Noel says the sum of the numbers with him is 16, he would have the numbers 3, 5, 8, leaving 2, 4, 6 for Nithin.

Answer:
9. Linda tells Tracy, “If you gave me one of your pens, then we would have the same number of pens.” Tracy replies, “If you gave me one of your pens, then I would have twice as many as you.”
If there are a total of 12 pens, then how many pens do Linda and Tracy have each?
Answer: Linda has 5 pens, and Tracy has 7 pens.
Explanation
Since the total number of pens is 12, let us assume Linda has 5 pens and Tracy has 7 pens.
If Linda gets one pen from Tracy, then she will have 6 pens, which are equal to Tracy’s after giving away one pen (7-1 = 6).
Tracy has 7 pens, and if Linda gives her one pen, then Tracy will have 7+1 = 8 pens, and Linda will be left with 4 pens (5-1 = 4).
10. There are 8 girls, and each girl has 8 backpacks. In each backpack, there are 8 big cats. There are 8 little cats for every big cat. How many legs are there in the bus, excluding the driver?
Answer: 18,448
Explanation
- Each girl has 8 backpacks, 8*8= 64 backpacks
- Each backpack has 8 cats, 64*8= 512 cats, one cat has four legs, 512*4= 2048 legs
- Each big cat has 8 little cats, 512*8= 4096, one cat has four legs, 4096*4= 16384 legs
- Eight girls have two legs each, 8*2= 16 legs
Total number of legs = 2048+16384+16 = 18,448
Math Puzzles For Class V (10-11 years)
11. Susan weighs half as much as Kate, and Brian weighs 3 times the weight of Susan. If the sum of their weights is 720 pounds, then how much does each of them weigh individually?
Answer:
Susan – 120 pounds
Kate – 240 pounds
Brian – 360 pounds
Explanation
Let Susan’s weight be x, then Kate’s weight will be 2x, and Brian’s will be 3x.
x + 2x + 3x = 720, then x = 720/6 = 120
So, individual weights are 120, 240, and 360 pounds.

Answer: Arithmetic and 88.5%
Explanation
Percentage marks in Hindi = 75/90*100 = 83.3%
Percentage marks in English = 85/100*100 = 85
Percentage marks in Arithmetic = 88/90*100 = 97.7%
He got the best percentage of marks in arithmetic.
Total marks he got = 75+85+88 = 248
Total marks = 90+100+90 = 280
Overall percentage= 248/280*100 = 88.5%
Jenna Laib says that using math place value puzzles makes her students hooked on solving them. She says, ”I scrapped my original plans for homework (and class), and instead assigned students to design their own “Inaba Place Value puzzles.” Students later worked through them when we had a spare moment in class. A few examples are shown at right. The sixth graders insisted on using more digits, and greater powers of 10. Whether in first grade, sixth, or eleventh, students seem to reach some consensus that problems are more complicated if the numbers in them are very large or very small (i).”
