Let the numbers = 5x and 7x

50x – 200 = 49x – 140
x = 60
So the answer = 7x – 5x = 2x = 2 × 60 = 120
Hence, Option B is correct.

Understanding the problem:
- Let the two numbers be 5x and 7x.
- According to the given information, (5x - 20)/(7x - 20) = 7/10.

Solving the equation:
- Cross multiplying, we get 10(5x - 20) = 7(7x - 20).
- Simplifying, we get 50x - 200 = 49x - 140.
- Solving for x, we get x = 60.

Finding the original numbers:
- The original numbers are 5x = 5 * 60 = 300 and 7x = 7 * 60 = 420.

Calculating the difference:
- The difference between the original numbers is 420 - 300 = 120.
Therefore, the correct answer is option B, 120.
