Answer:
20260275
Step-by-step explanation:
the question is same as selecting 4 things from 150 things
= C(150,4). (nCr formula)
=[150×149×148×147]÷[4×3×2×1]
= 49×75×149×37
= 20260275
Total marks for five tests = 85 * 5 = 425
Total marks in six tests with 90% would be: 90 * 6 = 540
So, the remaining marks will be: 540-425 = 115
Student must earn 115 grade in order to reach other average score of 90%
Hope this helps!
