Answer 1

Answer:

Step-by-step explanation:

(i) Number of correctly answered questions=20

   Marks scored=60

   number of incorrect answers by Amit=100-60=40

                                                                 =40/2        

                                                                 =20

(ii) Nitika Scored=-30

   number of incorrect answers=100-30=70

                                                                =70/2

                                                                 =35
