The Problem Statement
The problem states that the difference between a number and its two-fifth is 510. We need to find 10% of that number.
Step-by-Step Solution
1. Define the Number:
Let the unknown number be represented as 'x'.
2. Set Up the Equation:
According to the problem, the difference can be expressed as:
x - (2/5)x = 510
3. Simplify the Equation:
This simplifies to:
(3/5)x = 510
4. Solve for x:
To find x, multiply both sides by (5/3):
x = 510 * (5/3) = 850
5. Calculate 10% of x:
Now, to find 10% of the number:
10% of x = 10/100 * 850 = 85
Conclusion
The value of 10% of the number is 85. Therefore, the correct answer is option 'B'.
Key Takeaways
- The initial equation set up was essential to solving the problem.
- Simplifying and rearranging the equation allowed us to isolate the variable.
- Calculating percentages is straightforward once the base number is found.
This methodical approach confirms that the answer is indeed option 'B', which is 85.
