Answer 1

Step-by-step explanation:

marks obtained by each correct answer = 4

marks obtained by each incorrect answer = -2.

total no. of questions answered by Rahul = 30

no. of answers Rahul got correct = 25

= 25 × 4 = 100.

Rahul got 5 incorrect answers

so,

5 × ( -2 ) = -10

100 - 10 = 90.

Rahul's total score is 90.

hope this answer helps you dear....take care!

Answer 2

Answer:

Questions answered by Rahul = 30

Correct answers = 25

incorrect answers = 5

Marks given for every correct answer = -4 = 25×4 = 100

marks given for every incorrect answer = -4 = 5×(-2) = -10

marks get by Rahul = 100 - 10

= 90 Ans
