Q: A pie chart illustrates the time spent by students on various subjects. If 30% of the time is spent on Mathematics and 25% on Science, what percentage of time is spent on other subjects?
Solution: The percentage of time spent on other subjects is 100% - (30% + 25%) = 45%.
Steps: 6
Step 1: Understand that the total percentage of time spent on all subjects is 100%.
Step 2: Identify the percentage of time spent on Mathematics, which is 30%.
Step 3: Identify the percentage of time spent on Science, which is 25%.
Step 4: Add the percentages of Mathematics and Science together: 30% + 25% = 55%.
Step 5: Subtract the total percentage spent on Mathematics and Science from 100%: 100% - 55% = 45%.
Step 6: Conclude that 45% of the time is spent on other subjects.
