Answer:
Step-by-step explanation:
Ratio of adults to student is 2:5
If there are 12 more students than adults
Then, let adults be x
Then student is x+12
Total number =2x+12
Therefore,
Student =5/7 ×(2x+12)
x+12=(10x+60)/7
Cross multiply
7x+84=10x+60
7x-10x=60-84
-3x=-24
Divide both side by -3
x= -24/-3
x=8
The third option represent the solution.....
