The marks obtained by a student in a subject in three different tests were 20, 12, (-4). What are the total marks obtained by the student in that subject? What is the minimum number of marks he needs to score in the 4th test if the passing marks are 40?
[2 MARKS]
Total Marks: 1 Mark
Minimum Marks:1 Mark
The marks obtained by the student are
= 20, 12, (-4)
The total overall marks = 20 + 12 + (-4)
= 20 + 12 - 4
= 32 - 4
= 28
Given that
A student needs to score 40 in order to pass.
So, the number of marks the student needs to get on the 4th test to pass = 40 - 28 = 12
The student needs to score 12 marks in the 4th test to pass.
