Answer:

205

Step-by-step explanation:

total questions = 50

marks obtained per correct answer = 5

total correct answer scored by him = 42

Marks obtained for correct answers = 42×5 = 210

Total wrong answers = 5

marks deducted per wrong answer = -1

total marks deducted = -5

Marks scored by rahul = 210 - 5 = 205 Answer

Answer:

Number of marks for correct answers = +5marks

Number of marks for incorrect answers = -1 marks

Number of answers rahul attempted correctly = 42

Number of answers rahul attempted incorrectly = 5

Marks rahul scored for every correct answers = 42×5 = 210

Marks rahul scored for every incorrect answers = 5×-1 = -5

Total marks rahul scored in the test = 210 - 5 = 205.
