Please give me step by step solution ​

Answer 1

Answer:

Step-by-step explanation:

Mohan correct answers# 9   ---> Correct answer score = 9*5 = 45

Mohan incorrect answers# -> 20-9 =11  ---> Incorrect answer score = 11 * (-3 ) = (-33)

Mohan total score  

45 - 33 = 12

Rohan correct answers # - 10   ---> Correct answer score = 10*5 = 50

Rohan incorrect answers # = 20-10 =10  -> Incorrect answer score = 10 *(-3 ) = (-30)

Rohan total score  

50 - 30 = 20
