Answer:
Step-by-step explanation:
Answer: 110 marks.
Step-by-step explanation:
Here, marks given for every correct answer = 5 marks.
∴marks given for one incorrect answer = 3 marks.
If the student answers all the questions and gets 5 incorrect answers, then: (a)Number of correct answers=25(30-5)[x]
(b)Number of incorrect answers=5(as given)[y]
∴Let us say for any student who gave x right questions and y wrong questions then total marks are given as 5x-3y.
∴Total marks obtained by the student = 5(x)-3(y)
= 5(25)-3(5)
=125-15
=110.
Hope it helps. If it does; please appreciate my work by marking me as the brainliest.
