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

Difficulty: Easy

Correct Answer: 87.2%

Explanation:


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:

Total obtained = 45 + 47 + 49 + 45 + 32 = 218.Total maximum = 250.Percentage = (218 / 250) * 100% = 87.2%.


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%
