<h3>HOW TO CALCULATE TOTAL FROM MEAN?</h3>
The mean of a set of data can be calculated by dividing the total sum by the number of data given.
According to this question, Sara is said to have a mean score of 62 in 5 tests and another mean score of 68 in 6 tests.
- First total score = 62 × 5 = 310
- Second total score = 68 × 6 = 408
Therefore, Sara's score in the sixth test can be calculated by subtracting 310 from 408 to give 98.
