The marks that have to be scored in 6th test to make the average 85 is 105 .

What is Average ?

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 .
