Question

There are 25 students each in classes 6A 6B and 6C. They decide to donate newspapers, magazines and story books to orphanages.
Each student of 6A spends 30 on newspapers every month while in 6B each student spends Rs.50 on storybooks and 5C spends 40 every month on magazines. How much do all the students spend on these items throughout the entire year? What do you think about the students' initiative?

Answer 1

Hint: We will calculate money spent by each class by multiplying the number of students to the cost of donated stuff.
Then we will add all the expenditure by every class per month.
And then we will calculate for the whole year by multiplying the total money to 12.

Complete step-by-step answer:
It is given that number of students in each class $ = $ 25
Money spent by each student of 6A $ = $ 30 Rs. per month
Money spent by each student of 6B $ = $ 50 Rs. per month
Money spent by each student of 6C $ = $ 40 Rs. per month
Money spend by 6A per month $ = 25 \times 30 = Rs.750$
Money spend by 6B per month $ = 25 \times 50 = Rs.1250$
Money spend by 6C per month $ = 25 \times 40 = Rs.1000$
Total money spend per year $ = 3000 \times 12 = Rs.36000$
So, it is a very good initiative by students that they collect such a huge amount in donating useful stuff.
Total money spend by students per year $ = $ Rs.36000

Note: We can also solve questions for one student then we can calculate for the entire year.
Like – Total expenditure per student per month $ = 30 + 40 + 50 = Rs.120$
Expenditure per year per student $ = 120 \times 12 = Rs.1440$
Expenditure 25 students $ = 1440 \times 25 = Rs.36000$
