Answer 1

Answer:

a=22, b=60

Step-by-step explanation:

a=12*4-(8*2)=48-16=22

b=15*4=60

Answer 2

Answer:

a) Rajiv gets 12 correct answer and remaining incorrect

incorrect question = 20 - 12 = 8

Rajiv gets

12×4 = 48 mark for correct answer

and 8×(-2) = -16 mark for incorrect answer

His total score :-

= 48 + (-16)

= 48 - 16 = 32

b) Money gets 15 correct and rest not attempted

Not attempted questions = 20 - 15 = 5

Money gets

15 × 4 = 60 marks for correct answer

and 5 × 0 = 0 marks for not attempted question

His total score :-

60 + 0 = 60
