Answer 1

↑ Here is your answer ↓ _____________________________________________________________ _____________________________________________________________

She got 20 - 12 = 8 wrong answers

$12 * 4 = 48$

$8 * -2 = - 16$

Total marks

$= 48 + (-16)$

$=48-16$

$=32$

Answer 2

Answer:

here is your answer mate...

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.,

total score=32
