Analysis of Pooja's score:
Pooja scored 28 marks in total, with 4 marks given for each correct answer. Therefore, she must have answered 7 questions correctly (28/4 = 7). However, the question states that she only got 12 correct answers.
This means that Pooja answered 15 questions incorrectly (12 correct answers + 15 incorrect answers = 27 total answers).

Analysis of Anil's score:
Anil scored -12 marks in total, with -1 mark given for each incorrect answer. Therefore, he must have answered 12 questions incorrectly (-12/(-1) = 12). However, the question states that he got four correct answers.
This means that Anil answered 16 questions incorrectly (4 correct answers + 16 incorrect answers = 20 total answers).

Conclusion:
- Pooja answered 15 questions wrongly.
