Answer:
I got you
Step-by-step explanation:
2013 - 2000 students
2014 - 10% decrease of that of 2013
so, 10% of 2000 is 200.
Therefore, in 2014, there were 2000-200 students =1800
In 2015 - 10% increase of that of 2014.
so, 10% of 1800 is 180.
Therefore, in 2015, there were 1800+180 students = 1980.
Hence, in 2015, there were 1980 admissions in that particular school.
