Questions & Step-by-Step Solutions

A student scored 80% in Mathematics and 70% in Science. If both subjects are equally weighted, what is the average percentage?
  • Step 1: Identify the scores in each subject. The student scored 80% in Mathematics and 70% in Science.
  • Step 2: Add the two scores together. 80 + 70 = 150.
  • Step 3: Since both subjects are equally weighted, divide the total score by the number of subjects. There are 2 subjects, so divide 150 by 2.
  • Step 4: Calculate the average. 150 / 2 = 75.
  • Step 5: The average percentage is 75%.
  • Average Calculation – The process of finding the mean of two or more values by summing them and dividing by the number of values.
  • Weighted Average – Understanding that if subjects are equally weighted, the average can be calculated by simple arithmetic mean.
