Answer:50 marks
Step-by-step explanation:
No. of questions = 40
Every correct answer=+2 marks
Every wrong answer = -1 mark
No. of wrong answers = 10
∴ No of marks obtained is -10
∴ No. of correct answers is 40-10=30
∴ No. of marks obtained = 30 x 2
= 60 marks
∴ Total marks = 60 + (-10)
= 60 - 10
= 50
Total marks child obtains is 50
