Analyzing Mobile Phone Distribution Data

The question asks us to analyze data from a table showing the distribution of Mobile Phones under the CONNECT Scheme across different states and income groups. We need to find the difference in the number of phones distributed among High income people and Middle income people in Haryana, given a specific ratio for High and Low income percentages in that state.

Step-by-Step Solution for Haryana Mobile Phone Distribution

We are focusing on the data for Haryana. The table gives us the total number of Mobile Phones distributed in Haryana and the percentage distributed among Middle income people.

• Total Mobile Phones distributed in Haryana = 5.2 Lakhs.
• Percentage distribution among Middle income people in Haryana = 25%.

We are also given that the ratio of distribution percentage among High income people to Low income people in Haryana is 2:3.

Calculating Income Group Percentages in Haryana

For any state, the distribution percentages among High, Middle, and Low income people must add up to 100%.

Let:

• H% be the percentage for High income people in Haryana.
• M% be the percentage for Middle income people in Haryana.
• L% be the percentage for Low income people in Haryana.

We know M% = 25%.

So, H% + M% + L% = 100%

\(H\% + 25\% + L\% = 100\%\)

\(H\% + L\% = 100\% - 25\% = 75\%\)

We are given the ratio \(H\% : L\% = 2 : 3\).

The sum of the ratio parts is \(2 + 3 = 5\).

These 5 parts represent the remaining 75%.

Each ratio part represents \(\frac{75\%}{5} = 15\%\).

Now we can find H% and L%:

• H% (High income) = \(2 \times 15\% = 30\%\).
• L% (Low income) = \(3 \times 15\% = 45\%\).

Let's check: \(30\% + 25\% + 45\% = 100\%\). This is correct.

Calculating Number of Phones for Each Income Group in Haryana

The total number of phones in Haryana is 5.2 Lakhs, which is \(5.2 \times 100,000 = 520,000\) phones.

• Number of phones for High income people = H% of total phones in Haryana
• Number of phones for High income people = \(30\% \text{ of } 520,000\)
• Number of phones for High income people = \(0.30 \times 520,000 = 156,000\).

• Number of phones for Middle income people = M% of total phones in Haryana
• Number of phones for Middle income people = \(25\% \text{ of } 520,000\)
• Number of phones for Middle income people = \(0.25 \times 520,000 = 130,000\).

We are asked to find how many more phones were distributed among High income people than among Middle income people in Haryana.

Difference = (Number of phones for High income) - (Number of phones for Middle income)

Difference = \(156,000 - 130,000\)

Difference = \(26,000\).

So, the distribution of Mobile Phones among High income people in Haryana is 26,000 more than that among Middle income people.

Additional Information on Data Interpretation

Data interpretation questions often require careful reading of the table and the question. Here are some points to remember:

• Always note the units (e.g., Lakhs in this case).
• Pay attention to percentages and how they relate to the total or sub-totals.
• Missing values (-) need to be calculated using the information provided in the table or question.
• Ratios provide proportional relationships that can be used to find actual values or percentages.
• The total percentage for categories within a group (like income levels within a state) usually adds up to 100%, unless specified otherwise.

Understanding these concepts helps in solving data analysis problems accurately and efficiently during exams like those involving the CONNECT Scheme data.
