Answer 1

I can solve this

Step-by-step explanation:

Total no. of question = 20

now total score of test = 20×5

= 100

she answered three questions correctly

so marks for answering correct question = 3×5

= 15

*now she got -3 marks which means that she has attempted one wrong question

now this is clear that ina ll togather she has attempted 4 question so unattempted questions = 20-4=16

I hope it helps you :)
