The marks that have to be scored in 6th test to make the average 85 is 105 .
Average of a data set is the ratio of sum of all the data to the number of data in the set.
It is given that the average score = 81
Total tests up till now = 5
Total tests overall = 6
New Average = 85
Let the sum of the score for 5 tests is x
Then by the formula of average
x / 5 = 81
x = 405
Now let the marks scored in the 6th test is y
then ( 405 +y) / 6 = 85
405 + y = 510
y = 105
Therefore , the marks that have to be scored in 6th test to make the average 85 is 105 .
