In a 800 m race ,A gives some start to B and this makes the length of race for B 725 m. What start does B get from A ?

Options

A. 22 M
B. 35 m
C. 45 m
D. 75 m

Answer

To solve the problem, we need to determine the start that B gets from A in an 800 m race where B runs 725 m while A runs the full distance of 800 m.

### Step-by-Step Solution:

1. **Understand the Problem**:
- A runs a total distance of 800 meters.
- B runs a distance of 725 meters.
- We need to find out how much start (in meters) A gives to B.

2. **Identify the Distances**:
- Distance covered by A = 800 m
- Distance covered by B = 725 m

3. **Calculate the Start Given to B**:
- The start given to B can be calculated by finding the difference between the distance A runs and the distance B runs.
- Start given to B = Distance covered by A - Distance covered by B
- Start given to B = 800 m - 725 m

4. **Perform the Calculation**:
- Start given to B = 800 m - 725 m = 75 m

5. **Conclusion**:
- Therefore, the start that B gets from A is 75 meters.

### Final Answer:
B gets a start of **75 meters** from A.
