Answer:

25%

Explanation:

According to this question, a seek stored seeds of a rare and endangered plant. In order to ensure that the seeds remain fresh, 120 seeds are selected to be grown. However, out of these 120 seeds, only 90 germinated. This means that only 90 of 120 seeds are fertile.

This further means that (120-90) = 30 seeds are infertile and hence, could not germinate. In percentage, this can be represented as:

30/120 × 100

= 1/4 × 100

= 100/4

= 25% of the selected seeds are infertile.
