Questions & Step-by-Step Solutions
The average score of a student in five subjects is 72. If the student scores 80 in the sixth subject, what will be the new average?
Step 1: Find the total score of the student in the first five subjects. Since the average score is 72, multiply 72 by 5 (the number of subjects). This gives us 72 * 5 = 360.
Step 2: Add the score of the sixth subject (which is 80) to the total score from the first five subjects. So, 360 + 80 = 440.
Step 3: Now, to find the new average score, divide the total score (440) by the total number of subjects (which is now 6). So, 440 / 6 = 73.33.
Step 4: Round 73.33 to the nearest whole number, which is 74.
