total questions = 40
points for correct answer = 2
points for wrong answer = -1
questions attempted by child = 40
wrong answers = 12
score for wrong answers = 12 × (-1) = -12
correct answers = 40 - 12 = 28
score for correct answers = 28 × 2 = 56
total score of child = 56 + ( -12 ) ( + multiplied by - is -
= 56 - 12 = 44
Thus , the score of child is 44
points for correct answer = 2
points for wrong answer = -1
questions attempted by child = 40
wrong answers = 12
score for wrong answers = 12 × (-1) = -12
correct answers = 40 - 12 = 28
score for correct answers = 28 × 2 = 56
total score of child = 56 + ( -12 ) ( + multiplied by - is -
= 56 - 12 = 44
Thus , the score of child is 44

Answer:
The child will get a total score of 44 out of 80.
Step-by-step explanation:
As per the given information,
The child has attempted all the questions, out of which 12 are wrong.
∴ The number of correct answers= (40-12) = 28
The score for the correct answers= 28 × 2 = 56
The score to be deducted for the incorrect answers = 12 × (-1) = -12
∴ The final score of the child in the competitive exam
= [score for the correct answers] - [score deducted for the incorrect answers]
= 56 - 12
= 44
