Solution:
There are 65 students and 4 teachers
Each student got sweets that are 20% of the total number of students.
So each student got sweets = 65 × 20% = 13 sweets.
∴ Total sweets for students is = 65 × 13 = 845
Each teacher got sweets that are 40% of the total number of students.
So each teacher got sweets = 65 × 40% = 26 sweets.
There are 4 teachers, so total sweets for teachers = 4 × 26 = 104
∴ Total sweets = sweets for students + sweets for teachers
= 845 + 104 = 949
Therefore, the total number of sweets is 949.
