NUMBER PUZZLE

Question 1. I am thinking of two numbers. If I add the numbers, the total is 14. If I subtract the numbers, the difference is 4. If I multiply the numbers, the product is 45. Which two numbers am I thinking of?
Answer:
Let the two numbers be \(x\) and \(y\) where \(x > y\).
Sum: \(x + y = 14\)
Difference: \(x - y = 4\)
Adding both equations: \(2x = 18 \implies x = 9\)
Substituting \(x = 9\) in sum: \(9 + y = 14 \implies y = 5\)
Product check: \(9 \times 5 = 45\)
The two numbers are 9 and 5.
In simple words: Find two numbers that add up to 14, subtract to give 4, and multiply to 45.

Exam Tip: Verify all three conditions (sum, difference, and product) to confirm your answer.

Question 2. I am thinking of two numbers. If I add the numbers, the total is 48. If I subtract the numbers, the difference is 2. If I multiply the numbers, the product is 575. Which two numbers am I thinking of?
Answer:
Let the two numbers be \(x\) and \(y\) where \(x > y\).
Sum: \(x + y = 48\)
Difference: \(x - y = 2\)
Adding equations: \(2x = 50 \implies x = 25\)
Substituting \(x = 25\): \(25 + y = 48 \implies y = 23\)
Product check: \(25 \times 23 = 575\)
The two numbers are 25 and 23.
In simple words: Find two numbers whose sum is 48, difference is 2, and product is 575.

Exam Tip: Solving simultaneous linear equations quickly gives the two midpoint numbers.

Question 3. I am a two-digit number. I am a multiple of 11. The difference between my digits is 0. The sum of my digits is 12. What number am I?
Answer:
Let the number be represented by digits \(xy\).
Since the difference between digits is 0, \(x = y\).
The sum of digits is \(x + y = 12 \implies x + x = 12 \implies 2x = 12 \implies x = 6\).
Thus, both digits are 6, making the number 66.
Check: 66 is a multiple of 11 (\(11 \times 6 = 66\)) and sum of digits is \(6 + 6 = 12\).
The number is 66.
In simple words: A two-digit number with identical digits that add up to 12 and divide by 11.

Exam Tip: Two-digit multiples of 11 with identical digits are 11, 22, 33, 44, 55, 66, 77, 88, 99.

Question 4. I am a two-digit number. I am an odd number. The sum of my digits is 12. The units digit is three times bigger than the tens digit. What number am I?
Answer:
Let tens digit be \(t\) and units digit be \(u\).
Given: \(u = 3t\)
Sum of digits: \(t + u = 12 \implies t + 3t = 12 \implies 4t = 12 \implies t = 3\)
Units digit: \(u = 3 \times 3 = 9\)
The number is 39.
Check: 39 is an odd number, sum of digits \(3 + 9 = 12\), and units digit 9 is three times tens digit 3.
The number is 39.
In simple words: Find an odd two-digit number where digits sum to 12 and the second digit is three times the first.

Exam Tip: Ensure the final number satisfies the odd number condition.

Question 5. I am a prime number. I am less than 20. The product of my digits is 7. What number am I?
Answer:
Two-digit prime numbers less than 20 are 11, 13, 17, 19.
Check product of digits for each:
- For 11: \(1 \times 1 = 1\)
- For 13: \(1 \times 3 = 3\)
- For 17: \(1 \times 7 = 7\)
- For 19: \(1 \times 9 = 9\)
The number 17 gives a product of 7 and is a prime number less than 20.
The number is 17.
In simple words: A prime number below 20 whose digits multiply to give 7.

Exam Tip: List out all prime numbers in the given range before checking conditions.

Question 6. Find the two numbers, if their sum is 27, difference is 13 and the product is 140.
Answer:
Let the two numbers be \(x\) and \(y\) where \(x > y\).
Sum: \(x + y = 27\)
Difference: \(x - y = 13\)
Adding equations: \(2x = 40 \implies x = 20\)
Substituting \(x = 20\): \(20 + y = 27 \implies y = 7\)
Product check: \(20 \times 7 = 140\)
The two numbers are 20 and 7.
In simple words: Find two numbers that add up to 27, have a difference of 13, and multiply to 140.

Exam Tip: Simultaneous equations for sum and difference quickly isolate the larger and smaller numbers.
