Detailed Solution

Given
Minimum admission ticket sells in zoo per day = 350 Total students’ group = 4
Student in each group each = 48 Thus, overall ticket purchased by students =4(48) Additional ticket sold = z Therefore, overall ticket sold,

= 4 (48) + z

Now, overall ticket sold must be greater than equal to 350. Thus, the inequality expression,

4 (48) + z \geq 350

Correct option is 2.
