Direction: Study the data carefully and answer the questions given beside:

The graph shows the production and consumption of rice (in tonnes) in five different years in a particular area.

1
Find the average comsumption of rice (in tonnes) in year 2012, 2015 and 2016.
» Explain it
C
Comsumption of rice in 2012 = 6.4

Comsumption of rice in 2015 = 4.5

Comsumption of rice in 2016 = 7.82

Average consumption

6.4 + 4.5 + 7.82
3

18.72  = 6.24
3

Hence, option C is correct.
2
If the consumption of rice in 2013 is increased by 25% and the production of rice in same year is also increased by 10%, find the percentage of consumption in 2013.
» Explain it
E
Because consumption is increased by 25%,

Now consumption = 6.72 × 125% = 8.4

Production is increased by 10%,

Now production = 8.4 × 110% = 9.24

Percentage of consumption

8.4  × 100
9.24

= 90 10  %
11

Hence, option E is correct.
3
Find the ratio of the production of rice in 2012 and 2014 together to the consuption of rice in same year.
» Explain it
E
Production of rice in 2012 = 9.12

Production of rice in 2014 = 9.7

Consumption of rice in 2012 = 6.4

Consumption of rice in 2014 = 8.73

Required ratio = 9.12 + 9.7 : 6.4 + 8.73

= 18.82 : 15.13

= 1882 : 1513

Hence, option E is correct.
4
The consuption of rice in 2012 nd 2015 together is approximately how much percetange of the production of rice in 2014?
» Explain it
B
Consumption of rice in 2012 = 6.4

Consumption of rice in 2015 = 4.5

Production of rice in 2014 = 9.7

Required percentage

6.4 + 4.5  × 100
9.7

10.9  × 100 = 112.37% ≈ 112%
9.7

Hence, option B is correct.

5
If the production of rice in 2017 is 20% more than the production of rice in 2015 and the percentage of consumption is same as in 2015, find the consumption of rice in 2017.
» Explain it
C
Production of rice in 2015 = 7.5

Consumption of rice in 2015 = 4.5

Percentage of consumption

4.5  × 100 = 60%
7.5

Production of rice in 2017 = 7.5 × 120% = 9

Consumption of rice in 2017 = 9 × 60% = 5.4

Hence, option C is correct.
