Q: A student improved his score from 60% to 75% in a subject. What is the percentage increase in his score?
Solution:
Percentage increase = ((75 - 60) / 60) * 100 = (15/60) * 100 = 25%.
Steps: 7
Show Steps
Step 1: Identify the initial score, which is 60%.
Step 2: Identify the new score, which is 75%.
Step 3: Calculate the difference between the new score and the initial score: 75 - 60 = 15.
Step 4: Divide the difference by the initial score: 15 / 60.
Step 5: Convert the result into a percentage by multiplying by 100: (15 / 60) * 100.
Step 6: Simplify the calculation: 15 / 60 = 0.25, then 0.25 * 100 = 25%.
Step 7: The percentage increase in the student's score is 25%.
