To score at least 55% overall in an exam with 6 subjects, each worth 50 marks, you can follow these steps:

1. Total Marks Calculation:

   • Each subject is worth 50 marks.
   • With 6 subjects, the total marks possible are: $50 \times 6 = 300 \text{ marks}$

2. Required Marks for 55%:

   • To score 55% overall, you need 55% of the total marks: $0.55 \times 300 = 165 \text{ marks}$

3. Marks per Subject:

   • If you want the same score in every subject, you need to divide the required total marks by the number of subjects: $\frac{165}{6} \approx 27.5 \text{ marks per subject}$

So, you need to score at least 27.5 marks in every subject to achieve 55% overall.

Would you like any more details, or do you have any other questions? Here are some related questions you might find interesting:

1. How would the required marks change if one subject had a higher weight?
2. What would be the minimum passing marks per subject if you needed to pass each subject individually?
3. How does the percentage change if you score different marks in each subject?
4. How many marks would you need in the remaining subjects if you scored less in one?
5. How would the result change if the total marks were out of 600 instead of 300?

Tip: Always check if individual subjects have their own passing criteria, which might be higher than the overall percentage required.
