Cloud [144]

Answer:

Step-by-step explanation:

Data

2000   --------- 900 students

2001   ---------- 180

2002  ----------   ?

                               900 students ---------------- 100%

                               180 students  ----------------   x

                                x = (180 x 100) / 900

                                x = 20%

                               1080 students -------------  100 %

                               x                       -------------     20%

                               x = (20 x 1080) / 100

                              x = 216

                             

Total number of students = 1080 + 216 = 1296
