Answer 1

Answer:

Answer = 51

Step-by-step explanation:

Positive marks = 30,10,18,20

Total positive marks = 30+10+18+20 = 78

Negative marks = -7,-15,-5

Total Negative marks = [-7] + [-15] + [-5] = -27

Sum total = 78 + [-27]

                   78 - 27 = 51 Ans

Answer 2

Step-by-step explanation:

Ritu right answers = 30+10+18+20

Ritu wrong answers = -7+(-15)+-5

Total marks of test = 30+-7+(-15)+10+18+(-5)+20

add total marks = 51

Ritu correct answer = 30+10+18+20= 78

Ritu wrong answer=7+(-15)-5= -27

78 - 27

= 51
