What is her score?

Answer 1

Answer:(i)=40

              (ii)=7

Step-by-step explanation:(i) Meera's correct=10

                                              marks for correct=5*10=50

                                               Incorrect=15-10=5

                                               marks  for incorrect= -2*5 = -10    

                                               total marks=50-10=40

(ii)                                            correct=3

                                              marks for correct=3*10=15

                                               Incorrect=4

                                               marks  for incorrect= -2*4 = 8    

                                               total marks=15-8=7
