Solution:
Number of chocolate in first box = 135
Number of chocolate in second box = 145
Total number of chocolates = 135 + 145 = 280
(1 marks)
Total number of students = 300
Each students get 1 chocolate.
280 < 300
Since, total number of chocolate are less than number of students these boxes will not be sufficient for 300 students.
