Answer 2

Answer:

i- Number of correct answers he got=4

Marks awarded for each correct answer=5

marks he got= 5*4=20

Number of incorrect ans.=6

Marks deducted for wrong ans. = (-2)

total marks deducted= 6*2=12

Mohan got= 20-12

               =  8       Ans- Mohan got 8 marks.

ii-  Number of correct ans.= 2

   Marks she got= 5*2=10

    Number of incorrece ans.=5

    total marks deducted= 5*2=10

     Heena got = 10-10

    = 0                                                     Note- As 0 marks are given for not attempting a questions and zero has no value so we dont calculate it. Ans=0
