The estimate for the total number of bees in her hive is 190 bees

How to find the total estimate of the bees ?

She catches 90 of the bees on Monday and she puts mark on each bees and return them to her hive.

On Tuesday she catches 120 of the bees. She find out that 20 of the bees has been marked.

This means only 100 bees have not been marked on Tuesday.

total number = 90 + (120 - 20)

total number = 90 + 100

total number = 190 bees
