Data interpretation and logical reasoning

 

Q.1
Based on the data given below (Table 1.11) answer the questions following that.​

Find the number of crops for which India’s productivity is more than the world’s average productivity.
The productivity of certain crops in India is greater than the world’s average productivity. For each of these crops, what is the percentage difference between the world’s productivity and India’s productivity?
The difference between the productivity of cabbage in India and in tbe world is:

If beans production had occurred at it’s capacity for production for the entire world, then what would have been the estimated increment in the production in terms of:
absolute value increase ?
percentage increase ?
Represent the data above in the form of a set of:
bar charts.
pie charts.
line graph.

Ans .

1. Six
2. Eggplant 2.74%
Cauliflower 7.89%
Chilli 6.12%
Onion 2.85%
Pea 19.84%
Radish 0.36%
3. 59.4 g/ha
4. Chilli (green)
5. Cucumber
6. Chilli (green)
7. Cucumber
8. 31.96%
9. 62.16%
10. 59.20%
11. (a) Cannot be determined (b) 16.22%

Explanation :
1. Visual questions.
2. The required calculation would be = Differenceofproductivity[India−World]World′saverageproductivity
3.World′saverageproductivityofcabbage−India′sproductivityofcabbageIndia′sproductivityofcabbage
4-7. Use principals of maximisation and minimisation of ratio.
11.(a).The absolute value increase cannot be determined since we do not have any data about the amount of land under usage for the production of beans.
11.(b).The required value will be given by: 80−68.8368.83×100 = 80−68.8368.83×100

Q.2
Based on Figure 1.10 which gives the data of milk production in India from 198{}-81to 2001-412, answer the questions

In which year was the percentage increment in milk production the minimum?
For Question 7, find the percentage increment
Find the percentage growth in the milk production in India during the entire period.
Find the compounded annual percentage growth rate in the milk production in India during the entire period.
How much milk was produced in India during the entire period?
Represent the data above in the form of a set of:
bar charts.
pie charts.
table.

Ans .

1. 1998-99
2. 8.61%
3. 1998-99
4. 6.1 million litres
5. 1987-88
6. 1.30%
7. 1987-88
8. 1.30%
9. 180.37%
10. 5.03% approx
11. 1247.3 million litres

Explanation :
1. The maximum increment between two consecutive years will be given by the steepest slope. (clearly seen in 1998-99)
2. The percentage increment = 76.9−70.870.8×100 = 6.170.8×100.
3. A close inspection will make you compare between 1981-82 and 98-99. The ratios are 2.731.6 for 1981-82 and 6.170.8 for 98-99. You will need to calculate in the 0.1% range (for the percentage equivalents of these ratios).
4 – 8. The pattern of questioning is repetitive.
9. 88.6-31.6131.6 x 100 .
11. You will be required to calculate an approximate percentage value which will yield 88.6 from 31.6 in 21 years. Such calculations will not be required to be done in an examination context, so you need not worry about this question. Even if such a calculation is seemingly posed in the paper, there will definitely be a logical process to get to the correct answer.
