Puzzles for eyes only

Brain-Teaser 13 | Puzzles for Eyes Only | Coin Puzzles, Squares, Triangles & More | Key To Enjoy Learning Maths

🧠 Puzzles for Eyes Only

🪙 COIN PUZZLE
💰 By moving only one coin and using no others, you can put five coins in each leg.
💡 Solution: Move one coin from the intersection to the top of one leg
💡 This classic puzzle tests spatial thinking and creative problem-solving!
🔲 COUNTING SQUARES
❓ CAN YOU TELL HOW MANY SQUARES ARE THERE?
📐 Calculation:
5×5 = 25 squares
4×4 = 16 squares
3×3 = 09 squares
2×2 = 04 squares
1×1 = 01 square
Total = 55 squares
✅ ANSWER: 55 SQUARES
💡 Formula for an n×n grid: n² + (n-1)² + ... + 1² = n(n+1)(2n+1)/6. For n=5: 5×6×11/6 = 55.
🔢 NUMBER SERIES
❓ What number should replace the question mark?
🔍 Pattern:
2 + 1 = 3
2 + 3 = 5 + 1 = 6
6 + 3 = 9 - 1 = 8
8 + 6 = 14 + 1 = 15
8 + 15 = 23 - 1 = 22
22 + 38 = 60 - 1 = 59
✅ ANSWER: 59
💡 The pattern alternates between adding and subtracting 1 after each sum.
🔺 COUNTING TRIANGLES
❓ CAN YOU TELL HOW MANY TRIANGLES ARE THERE?
📐 Calculation:
5 + 5 = 10 triangles
4 + 4 = 08 triangles
3 + 3 = 06 triangles
2 + 2 = 04 triangles
1 + 1 = 02 triangles
Total = 30 triangles
✅ ANSWER: 30 TRIANGLES
💡 Count triangles of all sizes, both upward and downward pointing.
🦆 DUCK PUZZLE
❓ What is the smallest number of ducks that can swim in this formation: two ducks in front of a duck, two ducks behind a duck, and a duck between two ducks?
✅ ANSWER: 3 ducks (in a straight line)
💡 Explanation: Three ducks in a line: Duck A is in front of B and C, Duck C is behind A and B, and Duck B is between A and C. So two ducks are in front of the last duck, two behind the first, and one between the other two.
🚣 BOAT CROSSING
🚣 A boat will carry only 100 kg. How may a man weighing 100 kilograms and his two sons, each weighing 50 kilograms, use it to cross the river?
✅ Solution: The two sons go first. One son brings the boat back. The father crosses alone. Then the other son returns to pick up his brother.
📋 Step-by-step:
1. Both sons (50+50=100kg) cross together.
2. One son returns with the boat (50kg).
3. Father crosses alone (100kg).
4. The other son returns with the boat (50kg).
5. Both sons cross together again (100kg).
✅ All three are across!
💡 This is a classic river crossing logic puzzle that teaches sequential planning!
🐛 BOOKWORM PUZZLE
📚 A set of ten books is arranged in orderly fashion on a shelf. Each book has 100 pages, making 1000 pages in all. A worm starting on the first page of the first book eats through to the last page of the last book. How many pages has it eaten?
✅ ANSWER: 802 pages
💡 Explanation: The worm starts on the FIRST page of Book 1 (which is page 1 of the first book). It eats through the rest of Book 1 (99 pages), then all pages of Books 2 through 9 (8 books × 100 = 800 pages), but does NOT eat the first 99 pages of Book 10 (since it stops at the LAST page of the last book). Total = 99 + 800 + 1 = 800 + (99+1) = 800 + 100 = 900? Wait, let's recalc carefully! Actually: The worm does NOT eat the first 99 pages of Book 1 (only page 1) and does NOT eat the last 99 pages of Book 10? The classic answer is 802 pages eaten because the worm doesn't touch 99 pages of the first book and 99 pages of the last book.
