Answer:
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.
Answer:
Given,
TOTAL CORRECT ANSWER GIVEN BY GHANSHAM=7x5
=35
TOTAL INCORRECT ANSWER GIVEN BY GHANSHAM=5x2
=10
THEREFORE, TOTAL MARKS SCORED BY GHANSHAM=35-10=25
AGAIN,
TOTAL CORRECT ANSWER GIVEN BBY TEENA=5x5=25
TOTAL INCORRECT ANSWER GIVEN BY TEENA =5x2=10
THEREFORE, TOTAL MARKS SCORED BY TEENA =25-10=15
SO, GHANSHYAM SCORED MORE MARKS THAN TEENA
