Answer:

(i) Mohan get 4 correct answer = 4\times5\ =20\

He gets 6 incorrect answer = 6\times\left(-2\ \right)=\ -12

Total score = 20-12\ =\ 8\

Thus, mohan get 8 marks in the class test.

(ii) For 5 correct answer = 5\times5\ =\ 25

For 5 incorrect answer = 5\times\left(-2\right)=\ -10

Total score = 25-10\ =\ 15

(iii) Heena get 2 correct answer = 5\times2=\ 10

Heena get 5 incorrect = 5\times\left(-2\right)\ =\ -10
