Introduction

In a typical exam course, students are required to take multiple units to achieve a top grade. The mean mark of all units is a crucial factor in determining the overall grade. In this article, we will explore the concept of achieving top grade in a 6-unit exam course and provide a step-by-step solution to a problem involving a student named Tom.

Understanding the Concept of Mean Mark

The mean mark is calculated by adding up all the marks obtained in each unit and dividing the sum by the total number of units. For example, if Tom has taken 5 units and his mean mark is 78, it means that the sum of his marks in the 5 units is 78 x 5 = 390.

Problem Statement

Tom has taken 5 units and his mean mark is 78. To achieve top grade, the mean mark of all 6 units must be at least 80. How many marks must Tom get on the last unit to achieve top grade?

Step-by-Step Solution

To solve this problem, we need to follow these steps:

Step 1: Calculate the Total Marks Required for Top Grade

To achieve top grade, the mean mark of all 6 units must be at least 80. This means that the total marks required for top grade is 80 x 6 = 480.

Step 2: Calculate the Total Marks Obtained by Tom in 5 Units

Tom has taken 5 units and his mean mark is 78. This means that the total marks obtained by Tom in 5 units is 78 x 5 = 390.

Step 3: Calculate the Marks Required in the Last Unit

To achieve top grade, Tom needs to obtain a total of 480 marks. Since he has already obtained 390 marks in 5 units, he needs to obtain 480 - 390 = 90 marks in the last unit.

Conclusion

In conclusion, to achieve top grade in a 6-unit exam course, Tom needs to obtain at least 90 marks in the last unit. This is calculated by subtracting the total marks obtained by Tom in 5 units from the total marks required for top grade.
