25*4=100

5*2=10

Answer 2

Solution :-

Given : In a test 4 marks are given for every correct answer and (-2) marks for every incorrect answer.

Total number of questions = 30

Correct answers = 25

Incorrect answers = (30 - 25) = 5

Marks for 1 correct answer = 4

Marks for 25 correct answers = (25 × 4) = 100

Marks for 1 incorrect answer = (-2)

Marks for 5 incorrect answers = 5 × (-2) = - 10

Total marks = 100 + (-10)

= 100 - 10

= 90

Hence,

He gets 90 marks.
