Answer 2

Answer:

⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀According to the Question

It is given that in class test 4 marks were awarded for every correct answer , 2 marks were deducted for every incorrect answer & No marks were given for not attempting question .

No. of Marks Scored by Ravi = 20

No. of Correct answer given by him = 6

We have to calculate the No. of Question has he attempted incorrectly ? So, Let's Start

:\implies:⟹ Actual marks obtained by Ravi in giving correct answer = 12 × 3 = 36

But marks obtained by him = 20

Therefore,

→ marks cut in attempting incorrect Question = 36- 20

→ marks cut in attempting incorrect Question = -16

And , also the marks deducted for each incorrect answer is -2 . So ,

:\implies:⟹ The number of incorrect answer given by him = -16/-2

:\implies:⟹ The number of incorrect answer given by him = 16/2

:\implies:⟹ The number of incorrect answer given by him = 8

So , the number of questions he has attempted incorrectly was 8 .
