Calculation of the respective ratio between the number of female players from Georgia and the number of male players from the same country:

Identifying the number of female players from Georgia:
- Let's assume the number of female players from Georgia is represented by F.
- The number of female players from Georgia is not explicitly given in the question.

Identifying the number of male players from Georgia:
- The number of male players from Georgia is given as 69.

Calculating the ratio:
- The respective ratio between the number of female players from Georgia and the number of male players from the same country can be represented as F:69.

Using the options to find the correct ratio:
- Given options are:
a) 35:69
b) 32:69
c) 35:67
d) 32:67

- If we assume the number of female players from Georgia as 35, then the ratio becomes 35:69.
- This ratio matches option a) 35:69, which is the correct answer.

Therefore, the respective ratio between the number of female players from Georgia and the number of male players from the same country is 35:69.

According to the concept,
(12/20 × 15% + 16/20 × 12% + 40/50 × 30% + 80/100 × 10% + 14/20 × 33%)
⇒ (0.09 + 0.096 + 0.24 + 0.08 + 0.231) 
⇒ 0.737 or 73.7%
∴ The weighted average of the percentages she obtained in the five tests is 73.7%
