Answer 1

Answer:

Step-by-step explanation:

(i) Mohan get 4 correct answer = 4\times5\ =20\4×5 =20  

He gets 6 incorrect answer = 6\times\left(-2\ \right)=\ -126×(−2 )= −12

Total score = 20-12\ =\ 8\20−12 = 8  

Thus, mohan get 8 marks in the class test.

(ii) For 5 correct answer = 5\times5\ =\ 255×5 = 25

For 5 incorrect answer = 5\times\left(-2\right)=\ -105×(−2)= −10

Total score = 25-10\ =\ 1525−10 = 15

(iii) Heena get 2 correct answer = 5\times2=\ 105×2= 10

Heena get 5 incorrect = 5\times\left(-2\right)\ =\ -105×(−2) = −10

Total score = 10\ -10\ =\ 010 −10 = 0

Thus, total score of heena is zero.
