[tex](ANSWER)[/tex]

Let's assume the number of parrots Chandani purchased is "x".

According to the given information:

- 20% of the parrots flew away, so 80% of the parrots remained.

- 5% of the parrots died, so 95% of the remaining parrots remained.

- 45% of the remaining parrots were sold, so 55% of the remaining parrots remained.

So, we can write the equation:

0.55 * 0.95 * 0.8 * x = 33

Simplifying the equation:

0.418 * x = 33

Dividing both sides by 0.418:

x = 33 / 0.418

x ≈ 78.95

Therefore, Chandani had purchased approximately 79 parrots.

Answer:

80
