72 deer's

Step-by-step explanation:

Let the number of deer be x.

As per the condition, we have

\frac { x }{ 2 } deer are grazing in the field.

NCERT Solutions for Class 8 Maths Chapter 2 Linear Equations in One Variable Ex 2.4 Q8

⇒ 4x + 3x + 72 = 8x

⇒ 7x + 72 = 8x

⇒ 72 = 8x – 7x (Transposing 7x to RHS)

⇒ x = 12

Hence, the required number of deer = 72.
