{'percentage': [1, 2, 2, 3], 'mathematics': [0, 1, 0, 0], 'ratio': [1, 0, 1, 12], 'chemistry': [0, 2, 4, 5], 'physics': [0, 2, 3, 4], 'examination': [0, 0, 1, 1], 'passes': [1, 0, 0, 2], 'chemistty': [0, 0, 0, 1]}

To solve this question, let`s first analyze the information given.

We are given the following percentages of students who passed in each subject:

- Mathematics: 53%

- Physics: 61%

- Chemistry: 60%

We are also given the percentages of students who passed in specific combinations of subjects:

- Mathematics and Physics: 24%

- Physics and Chemistry: 35%

- Mathematics and Chemistry: 27%

- None of the subjects: 5%

To find the ratio of the percentage of passes in Mathematics and Chemistry but not in Physics to the percentage of passes in Physics and Chemistry but not in Mathematics, we need to compare the overlaps between these subjects.

We know that the overlap between Mathematics and Physics is 24%, between Physics and Chemistry is 35%, and between Mathematics and Chemistry is 27%.

To find the percentage of passes in Mathematics and Chemistry but not in Physics, we can subtract the percentage of passes in Mathematics and Physics from the percentage of passes in Mathematics and Chemistry:

27% - 24% = 3%

To find the percentage of passes in Physics and Chemistry but not in Mathematics, we can subtract the percentage of passes in Mathematics and Physics from the percentage of passes in Physics and Chemistry:

35% - 24% =
