The total number of deer in the group is 16.
Step-by-step explanation:
Given:
Let us assume that the total number of deer is x
Here it is given that out of a group of deer, the total number are grazing grass and remaining two are playing.
Also it is given that number of deer grazing grass =
Remaining deer who are playing = 2
Therefore total number of deer in the group will be,
So, squaring both the sides, we get
4x(x-16)-1(x-16) = 0
(x-16)(4x-1) = 0
x - 16 = 0 or 4x-1 = 0
x = 16 or [It is not possible]
Therefore, x = 16
The total number of deer in the group is 16.
