Answer 1

The population density of an insect species increases from 40 to 46 in one month if the birthrate during that period is 0.4, then the death rate should be 0.25.

As birth rate is 0.4 means 40 insect should produce 16 insect.

Out of 16 6 persist and 10 died that means 10/40. So the death rate should be 0.25.
