Sahil scores: Hindi 45, Science 47, Mathematics 49, Social Science 45, and English 32 (each subject out of 50). What is his overall percentage?

Introduction / Context: Compute the total obtained marks over the total maximum marks and convert to a percentage. All subjects have equal maximum marks, simplifying the calculation.

Given Data / Assumptions:

• Scores: 45, 47, 49, 45, 32.
• Maximum per subject = 50.
• Number of subjects = 5.

Concept / Approach: Total obtained = sum of individual scores. Total maximum = 5 * 50 = 250. Percentage = (obtained / maximum) * 100%.

Step-by-Step Solution:

Verification / Alternative check: 10% of 250 is 25; subtracting 7.8 from 100 gives 92.2? That route is error-prone; stick to direct fraction 218/250 = 0.872.

Why Other Options Are Wrong: 75% or 78% underestimate; 56.4% mis-sums marks.

Common Pitfalls: Arithmetic errors when summing or dividing by 250; forgetting each subject has the same maximum.

Final Answer: 87.2%
