Thetotalscore=32
Step-by-step explanation:
Suppose the number of correct answered questions be 'x' , then number of wrongly answer questions = (20-x).
It is given that for every correct answer 4 marks are awarded .
Number of marks scored for correct answers = 4x
And it is given that for every wrongly answered question ' 2 ' marks are deducted .
Number of marks to be deducted from the score = (20-x) × 2 = 40 - 2x ,
Total Score = 4x - ( 40 - 2x )
= 4x - 40 + 2x
= 6x - 40
But it is given that x = 12( correct answered questions)
= 6 × 12 - 40
= 72 - 40
= 32
Therefore \: \red { The \: total \:score } \green {= 32 }ThereforeThetotalscore=32
