Do you have a picture of your question?
Q1 = -12.4 letter D
Q2 = 7/9 letter A
Q3 = -1/5 letter B
Q4 = 0.2 letter C
Once I got the letters, I just looked for the symbols on the table and letter D on the table for Q1 is the last picture, for Q2 is the brain, Q3 = sand clock and Q4 is the third picture, so the code is below.
This is the code
Code: 5, 7, 0, 5
