Answer 1

SOLUTION:-

GIVEN:-

Total class test containing questions=25

marks cut for incorrect questions=13×10=130

=130-5×5

=130-25

=105Answer

Answer 2

Answer:

The marks scored by the student is 30

Step-by-step explanation:

So let us say for any student who gave x right questions and y wrong questions then total marks is given as 5x+(−2)y i.e 5x−2y total marks.

5 × 8 - 2 × 5 =

40 - 10 =

30
