Question
In a class of 50 students and 20 teachers, each student
got gifts that were 24% of total number of students and each teacher got gifts that were 16% of total number of students. How many gifts were there in total?Solution
Gifts received by each student = 24% of total number of students i.e. => 24/100 × 50 = 12 Gifts received by each teacher = 16% of total number of students i.e. => 16/100 × 50 = 8 Total Gifts = 50 × 12 + 8 × 20 = 760
