Question

Get data from your school office on the total fee charged for admission to Class XI, between the period 2011-2018. Plot the data on graph paper. Read the arithmetic line graph carefully and write your observation.

Answer 1

Year	2011 − 12	2012 − 13	2013 − 14	2014− 15	2015− 16	2016 − 17	2017 −18
Fees	10000	10500	13000	12000	14000	14500	15250

Observation: From the above graph, we can observe that the school has increased the fee charged for admission to class XI, from the academic year 2011-12 till 2013-14. However, in the year 2014-15 the school decreased the fee amount from Rs 13,000 to Rs 12,000 after which the school fee was again increased from the year 2015-16 till 2017-18.
