Question 154

In a class of 30 students and 2 teachers, ‘each student got sweets that are 20% of the total number of students and each teacher got sweets that are 30% of the total number of students. How many sweets were there ?

Solution

There are 30 students and 2 teachers.

Sweets received by each student = $$\frac{20}{100} * 30$$ = 6

=> Total sweets received by all the students = 30 * 6 = 180

Sweets received by each teacher = $$\frac{30}{100} * 30$$ = 9

=> Total sweets received by both teachers = 2 * 9 = 18

$$\therefore$$ Total sweets distributed in class = 180 + 18 = 198
