Q: A student scored 75% in Mathematics and 85% in Science. If the weightage of Mathematics is 40% and Science is 60%, what is the overall percentage score of the student? (2023)

Solution: Overall percentage = (75% * 0.4) + (85% * 0.6) = 30% + 51% = 81%.

Steps: 7

Step 1: Identify the scores in each subject. The student scored 75% in Mathematics and 85% in Science.
Step 2: Identify the weightage of each subject. Mathematics has a weightage of 40% and Science has a weightage of 60%.
Step 3: Convert the weightage percentages into decimal form. 40% becomes 0.4 and 60% becomes 0.6.
Step 4: Calculate the weighted score for Mathematics by multiplying the score by its weightage: 75% * 0.4 = 30%.
Step 5: Calculate the weighted score for Science by multiplying the score by its weightage: 85% * 0.6 = 51%.
Step 6: Add the weighted scores from both subjects together: 30% + 51% = 81%.
Step 7: The overall percentage score of the student is 81%.
