Answer:
90
Step-by-step explanation:
Since the average of 5 tests is 60, we can find the sum of the five tests.
(Sum of five tests) / 5 = 60
Sum of five tests = 300
Now, we can find the marks in the 6th test
(Sum of 5 tests + 6th test marks) / 6 = 65
(300 + x)/6 = 65
x = 390 - 300
x = 90
Therefore, the marks in the 6th test = 90
