Answer 1

Given :-

In  a class test containing 15 questions, 4 marks are given for the every correct answer and (-1) for  every incorrect answer.  

(b) Ram answered all questions and 7 of his answers are wrong.

To Find :-

Score of Ram

Solution :-

Total question = 15

Wrong answer = 7

Correct answer = 15 - 7 = 8

Score = Correct answer + Incorrect answer

Score = 8(4) + (-1)(7)

Score = 32 + (-7)

Score = 32 - 7

Score = 25

Answer 2

Answer:

25 marks

Step-by-step explanation:

Because

15 questions

Each question contains 4 marks then

15×4 = 60 total mark

then

7 questions wrong

7×4 = 28

for every wrong answer minus mark = -1

7× 1 = 7

wrong question 28+minus mark 7= 35

total mark-wrong answer = scored mark

60- 35 = 25

Ram scored 25 marks in his test
