In a class of 70 students and 25 teachers, each student
got gifts that were 20% of total number of students and each teacher got gifts that were 10% of total number of students. How many gifts were there in total?Solution
Gifts received by each student = 20% of total number of students i.e. => 20/100 × 70 = 14 Gifts received by each teacher = 10% of total number of students i.e. => 10/100 × 70 = 7 Total Gifts = 70 × 14 + 7 × 25 = 1155
