1. The problem is to calculate the final grade based on the status of questions, ignoring the white squares. 2. We have 61 questions in total. 3. Pink squares are at questions 7, 11, 16, 23, 30, 49, 61, which we interpret as incorrect or negative. 4. White squares at 4, 29, 41, 42 are ignored as per the instruction. 5. The rest of the questions are green, which we interpret as correct or positive. 6. Count the number of pink squares: 7. 7. Count the number of white squares: 4 (ignored). 8. Count the number of green squares: total questions - pink - white = 61 - 7 - 4 = 50. 9. Assuming each question has equal weight, the grade is the ratio of correct answers (green) to total answered questions (green + pink). 10. Total answered questions = 50 + 7 = 57. 11. Grade = \frac{50}{57}. 12. Simplify the fraction if possible or convert to percentage. 13. Calculate percentage: $$\frac{50}{57} \times 100 \approx 87.72\%$$. 14. Final grade is approximately 87.72%.
