Calculating Newspaper Distribution Percentage

The question asks us to find the percentage of newspapers distributed compared to the total number of newspapers printed. We are given a table showing the number of newspapers printed for four different newspapers (A, B, C, D) and the number distributed in four different cities (Delhi, Lucknow, Varanasi, Jaipur).

Understanding the Data Table

The table provides two key pieces of information for each newspaper:

• The number printed (shown in brackets next to the newspaper name).
• The number distributed in each specific city.

Let's summarize the data from the table:

Step 1: Calculate the Total Number of Newspapers Printed

The total number of newspapers printed is the sum of the number printed for each newspaper.

Total Printed = Newspaper A Printed + Newspaper B Printed + Newspaper C Printed + Newspaper D Printed

Total Printed = ${2000 + 2000 + 1000 + 1000}$

Total Printed = ${6000}$

Step 2: Calculate the Total Number of Newspapers Distributed

The total number of newspapers distributed is the sum of the number distributed across all cities for all newspapers. We can calculate this by summing the distributed numbers column-wise (by newspaper) or row-wise (by city).

Let's sum city-wise:

• Total Distributed in Delhi = ${1000 + 750 + 320 + 250 = 2320}$
• Total Distributed in Lucknow = ${500 + 250 + 250 + 175 = 1175}$
• Total Distributed in Varanasi = ${200 + 150 + 165 + 155 = 670}$
• Total Distributed in Jaipur = ${200 + 350 + 135 + 160 = 845}$

Total Distributed = Total in Delhi + Total in Lucknow + Total in Varanasi + Total in Jaipur

Total Distributed = ${2320 + 1175 + 670 + 845}$

Total Distributed = ${5010}$

Alternatively, we could sum newspaper-wise:

• Total Distributed for Newspaper A = ${1000 + 500 + 200 + 200 = 1900}$
• Total Distributed for Newspaper B = ${750 + 250 + 150 + 350 = 1500}$
• Total Distributed for Newspaper C = ${320 + 250 + 165 + 135 = 870}$
• Total Distributed for Newspaper D = ${250 + 175 + 155 + 160 = 740}$

Total Distributed = Total for A + Total for B + Total for C + Total for D

Total Distributed = ${1900 + 1500 + 870 + 740}$

Total Distributed = ${5010}$

Both methods give the same total distributed number, which is ${5010}$.

Step 3: Calculate the Percentage of Distributed Newspapers Compared to Printed Newspapers

The percentage is calculated using the formula:

Percentage = $(\frac{\text{Total Distributed}}{\text{Total Printed}} \times 100\rpar;\text{%}$

Substitute the calculated values:

Percentage = $(\frac{5010}{6000} \times 100\rpar;\text{%}$

Percentage = ${0.835 \times 100}\text{%}$

Percentage = ${83.5}\text{%}$

So, the percentage of distributed newspapers compared to printed newspapers is ${83.5}\text{%}$.

Additional Information: Calculating Percentage from Data

When working with data tables like this, calculating percentages is a common task. The basic principle is always the same:

Percentage = $(\frac{\text{Part}}{\text{Whole}} \times 100\rpar;\text{%}$

In this specific problem:

• The 'Part' is the total number of newspapers distributed.
• The 'Whole' is the total number of newspapers printed.

Understanding which number represents the 'part' and which represents the 'whole' is crucial for accurate percentage calculation. The 'whole' is usually the initial or total amount against which the 'part' is compared.

Data tables often require summing up various entries to get the required 'part' or 'whole' totals before the percentage calculation can be done. Always read the question carefully to identify exactly what percentage is being asked for.
