The sum of digits of a two-digit number is 14 and the difference between the two digits of the number is 2. The product of the two digits of the number is:
Answer & explanation
Correct answer: option 3
The correct answer is Option (3) → 48
1. Define the Variables
Let the two digits of the number be $x$ and $y$.
2. Set Up the Equations
- Sum of the digits: $x + y = 14$
- Difference between the digits: $|x - y| = 2$
We can solve this using the two possible scenarios for the difference:
Case 1: $x - y = 2$
Adding the two equations:
$(x + y) + (x - y) = 14 + 2$
$2x = 16$
$x = 8$
Now, substitute $x = 8$ back into the first equation:
$8 + y = 14$
$y = 6$
Case 2: $y - x = 2$
Following the same logic, we would find that $y = 8$ and $x = 6$.
In both cases, the two digits of the number are 6 and 8. (The number is either 68 or 86).
3. Calculate the Product
The question asks for the product of these two digits:
$\text{Product} = 6 \times 8 = 48$
Conclusion
The product of the two digits of the number is 48.
