   Solution –

   ⠀In the Question; It is concluded that ravi hits total 20 Marks in the class test and 4 marks are rewarded for every correct answer. If he gets wrong answer then his 2 marks will be deducted from the test. No marks will be given for skipped question, He got 8 answers as correct: So, How many answers he has given wrong? Let’s find out..

   [tex]\:\:\:\:\:\:\twoheadrightarrow[/tex] No. of correct answer = 8

   [tex]\:\:\:\:\:\:\twoheadrightarrow[/tex] For correct answers = 8(4) = 32

   [tex]\:\:\:\:\:\:\twoheadrightarrow[/tex] His total score = 20

   Now –

   ⠀— We have the required marks that he secured in his class test that is 32. But.. Now we have to find the no. of answers that he hit incorrectly

   ⠀— Let the no. of incorrect answer be x

   As, 2 Mark’s will be taken away for Incorrect answer.. So, It should be 2x.

   So, for incorrect answers = 32 – 20 = 12

   [tex]\longrightarrow\sf{\: 2x = 12}[/tex]

   [tex]\longrightarrow\sf{\: x = \dfrac{12}{2}}[/tex]

   [tex]\longrightarrow\underline{\sf{\red{\: x = 6}}}[/tex]

   Final Answer –

   ⠀⠀⠀— Hence, He scored total 32 marks and he got 6 answer as incorrect in his class test
