In the following table, production of corn (in tonnes) of three different states Kashmir, Kerala and UP over the years 2014 to 2017 is shown.

Years States	2014	2015	2016	2017
Kashmir	8.2	6.8	4.2	7
Kerala	7.6	6.2	5	5.4
U.P.	7.2	7	5.8	5.6

What is the difference between the total production of corn (in tonnes) by all the three states in the years 2016 and 2017?

Correct option is C

Solution:

the total production of corn in 2016:

​Kashmir: 4.2 tonnes

Kerala: 5 tonnes

UP: 5.8 tonnes

Total production in 2016 = 4.2 + 5 + 5.8 = 15 tonnes

the total production of corn in 2017:

Kashmir: 7 tonnes

Kerala: 5.4 tonnes

UP: 5.6 tonnes

Total production in 2017 = 7 + 5.4 + 5.6 = 18 tonnes

the difference in production:

​Difference = 2017 production - 2016 production = 18 tonnes - 15 tonnes = 3 tonnes

Therefore, the difference between the total production of corn by all three states in the years 2016 and 2017 is 3 tonnes.

Thus, option (C) is right answer.
