Question

A park ranger calculated that 60% of the deer they tagged were male. Of the male deer that were tagged, 20% of them were older than 4 1/2 years. They tagged 18 male deer that were older than 4 1/2 years. How many deer did they tag?

Answer 1

60% of the deer tagged were male.....40% were female
of the male deer, 20% were older then 4 1/2 years....and 18 male deer were older then 4 1/2 years...
so 20% of the male deer tagged = 18
0.2x = 18
x = 18 / 0.2
x = 90....so there were 90 male deer that were tagged

thats means 60% of the total deer = 90
0.6x = 90
x = 90/0.6
x = 150 <=== so there were a total of 150 deer tagged (male and female)
