The following table shows the percentage (%) distribution of wheat production in seven different countries, namely, India, China, Japan, Srilanka, Indonesia, Pakistan and Bangladesh by deploying Scientific Method and Conventional Method. Total production of wheat in these countries is 50 lakh tonnes. Based on the data in the table, answer the questions that follow Country-wise Distribution of Wheat Production Country Distribution (%) of Wheat Production (out of 50 lakh tonnes) Distribution (%) of Wheat Production Scientific Method Conventional Method India 18% 32% 68% China 22% 70% 30% Japan 20% 78% 22% Srilanka 13% 60% 40% Indonesia 10% 73% 27% Pakistan 9% 66% 34% Bangladesh 8% 20% 80%
Production of wheat in Srilanka by the Conventional Method is approximately ______ times the production of wheat in India by the Scientific Method.
Understanding Wheat Production Data Analysis
The question asks us to compare the wheat production in Srilanka using the Conventional Method with the wheat production in India using the Scientific Method, based on the provided table.
We are given the total wheat production across seven countries is 50 lakh tonnes. The table provides the percentage distribution of this total production for each country and also the percentage distribution of production within each country by Scientific Method and Conventional Method.
Step-by-Step Calculation of Wheat Production
1. Calculate Total Wheat Production for Srilanka
The table shows that Srilanka accounts for 13% of the total wheat production.
Total production in Srilanka = 13% of 50 lakh tonnes
Total production in Srilanka = $\frac{13}{100} \times 50$ lakh tonnes
Total production in Srilanka = $\frac{650}{100} = 6.5$ lakh tonnes.
2. Calculate Wheat Production in Srilanka by Conventional Method
The table shows that 40% of Srilanka's total wheat production is done by the Conventional Method.
Production in Srilanka by Conventional Method = 40% of Total production in Srilanka
Production in Srilanka by Conventional Method = $\frac{40}{100} \times 6.5$ lakh tonnes
Production in Srilanka by Conventional Method = $0.4 \times 6.5 = 2.6$ lakh tonnes.
3. Calculate Total Wheat Production for India
The table shows that India accounts for 18% of the total wheat production.
Total production in India = 18% of 50 lakh tonnes
Total production in India = $\frac{18}{100} \times 50$ lakh tonnes
Total production in India = $\frac{900}{100} = 9$ lakh tonnes.
4. Calculate Wheat Production in India by Scientific Method
The table shows that 32% of India's total wheat production is done by the Scientific Method.
Production in India by Scientific Method = 32% of Total production in India
Production in India by Scientific Method = $\frac{32}{100} \times 9$ lakh tonnes
Production in India by Scientific Method = $0.32 \times 9 = 2.88$ lakh tonnes.
5. Find the Ratio
We need to find how many times the production of wheat in Srilanka by the Conventional Method is compared to the production of wheat in India by the Scientific Method.
Ratio = $\frac{\text{Production in Srilanka by Conventional Method}}{\text{Production in India by Scientific Method}}$
Ratio = $\frac{2.6 \text{ lakh tonnes}}{2.88 \text{ lakh tonnes}}$
Ratio $\approx 0.9027$
6. Approximate the Result
The question asks for the approximate value. The calculated ratio $0.9027$ is approximately $0.9$.
Summary of Calculations
| Country | % of Total Production | Total Production (lakh tonnes) | % by Scientific Method | % by Conventional Method | Production by Scientific Method (lakh tonnes) | Production by Conventional Method (lakh tonnes) |
|---|---|---|---|---|---|---|
| Srilanka | 13% | 6.5 | 60% | 40% | $0.6 \times 6.5 = 3.9$ | $0.4 \times 6.5 = 2.6$ |
| India | 18% | 9 | 32% | 68% | $0.32 \times 9 = 2.88$ | $0.68 \times 9 = 6.12$ |
Ratio = $\frac{2.6}{2.88} \approx 0.9$
Therefore, the production of wheat in Srilanka by the Conventional Method is approximately 0.9 times the production of wheat in India by the Scientific Method.
Revision Table: Wheat Production Analysis
- Understand the total production value (50 lakh tonnes).
- Identify the percentage share of each country in total production.
- Calculate the total production for the specific countries (India and Srilanka).
- Identify the percentage share of each method (Scientific/Conventional) within the country's production.
- Calculate the production by the specified method for each country.
- Formulate the ratio required by the question.
- Perform the division and approximate the result to match the options.
Additional Information: Data Interpretation Skills
Data interpretation questions like this require careful reading of the table and question. Key skills include:
- Calculating percentages of given values.
- Calculating percentages of percentages.
- Setting up ratios and proportions.
- Approximating values accurately when required.
- Extracting specific data points from a larger dataset.
Practicing with different types of data representation (tables, charts, graphs) helps improve these skills for exam preparation.
