2)

total no.of multiple questions are 120

let no.of correct answers=x

and no.of incorrect answers = 120-x

marks for correct answers=x×1

                                           =x

marks for incorrect answers=(120-x)1/4

                                              =60-x/2

marks scored =80

x-(30-x/4)=80

x-30+x/4 =80

x+x/4 = 110

5 x/2 = 110

5 x=110 ×2

x=22×2

x=44

hope you understand
