Data Interpretation Questions

Multiple choice

Consider a pie chart that displays the distribution of agricultural produce in the state of Punjab, India. If the pie chart indicates that 30% of the total produce is wheat, what is the percentage of other crops combined?

  1. 30%

  2. 50%

Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

Since the pie chart represents the entire agricultural produce of Punjab, the percentage of other crops combined must be the remaining portion after subtracting the percentage of wheat. Therefore, 100% - 30% = 70%.

Multiple choice

A Correct answer
Explanation

To calculate the approximate population of the North Indian region, we can use the proportion represented by the pie chart. 40% of 1.3 billion is (40/100) * 1.3 billion = 0.4 * 1.3 billion = 520 million.

Multiple choice

A pie chart compares the literacy rates in different states of India. If the pie chart indicates that the state of Kerala has a literacy rate of 95%, what is the approximate difference in literacy rate between Kerala and the state with the lowest literacy rate, which is 55%?

  1. 30%

  2. 40%

  3. 50%

  4. 60%
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

To calculate the approximate difference in literacy rate, we can subtract the literacy rate of the state with the lowest literacy rate from that of Kerala. 95% - 55% = 40%.

Multiple choice

Consider a pie chart that displays the distribution of mineral resources in the state of Jharkhand, India. If the pie chart indicates that 45% of the total mineral resources are coal, what is the percentage of other minerals combined?

  1. 45%

  2. 55%

  3. 65%

  4. 75%
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

Since the pie chart represents the entire mineral resources of Jharkhand, the percentage of other minerals combined must be the remaining portion after subtracting the percentage of coal. Therefore, 100% - 45% = 55%.

Multiple choice

A pie chart shows the distribution of rainfall in different seasons in the state of Meghalaya, India. If the pie chart indicates that the monsoon season accounts for 70% of the total rainfall, what is the approximate amount of rainfall received during the monsoon season if the total annual rainfall in Meghalaya is 11,800 mm?

  2. 5,900 mm

  3. 3,540 mm

  4. 10,620 mm
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

To calculate the approximate amount of rainfall received during the monsoon season, we can use the proportion represented by the pie chart. 70% of 11,800 mm is (70/100) * 11,800 mm = 0.7 * 11,800 mm = 8,260 mm.

Multiple choice

  1. 1,000

  2. 1,500

  3. 2,000

  4. 2,500
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

To calculate the approximate difference in population density, we can subtract the population density of the district with the lowest population density from that of Lucknow. 2,000 - 500 = 1,500.

Multiple choice

A pie chart shows the distribution of agricultural land use in different regions of India. If the pie chart indicates that the North-Eastern region accounts for 10% of the total agricultural land, what is the approximate area of agricultural land in the North-Eastern region if the total agricultural land in India is 150 million hectares?

  1. 15 million hectares

  2. 25 million hectares

  3. 35 million hectares

  4. 45 million hectares
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

To calculate the approximate area of agricultural land in the North-Eastern region, we can use the proportion represented by the pie chart. 10% of 150 million hectares is (10/100) * 150 million hectares = 0.1 * 150 million hectares = 15 million hectares.

Multiple choice

A pie chart compares the number of tourists visiting different states in India. If the pie chart indicates that the state of Rajasthan receives 20% of the total tourist arrivals, what is the approximate number of tourists visiting Rajasthan if the total number of tourist arrivals in India is 10 million?

  1. 1 million

  2. 2 million

  3. 3 million

  4. 4 million
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

To calculate the approximate number of tourists visiting Rajasthan, we can use the proportion represented by the pie chart. 20% of 10 million is (20/100) * 10 million = 0.2 * 10 million = 2 million.

Multiple choice

Consider a pie chart that displays the distribution of electricity generation in India by different sources. If the pie chart indicates that thermal power plants contribute 65% of the total electricity generated, what is the percentage of electricity generated from other sources combined?

  1. 15%

  2. 25%

  3. 35%

  4. 45%
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

Since the pie chart represents the entire electricity generation in India, the percentage of electricity generated from other sources combined must be the remaining portion after subtracting the percentage of thermal power plants. Therefore, 100% - 65% = 35%.

Multiple choice

A pie chart shows the distribution of GDP contribution by different sectors in the state of Maharashtra, India. If the pie chart indicates that the services sector contributes 60% of the total GDP, what is the approximate contribution of the industrial sector if the total GDP of Maharashtra is ₹20 trillion?

  1. ₹6 trillion

  2. ₹8 trillion

  3. ₹10 trillion

  4. ₹12 trillion
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

To calculate the approximate contribution of the industrial sector, we can use the proportion represented by the pie chart. Since the services sector contributes 60%, the industrial sector must contribute the remaining 40%. Therefore, 40% of ₹20 trillion is (40/100) * ₹20 trillion = 0.4 * ₹20 trillion = ₹8 trillion.

Multiple choice

A pie chart compares the number of internet users in different states of India. If the pie chart indicates that the state of Karnataka has 25 million internet users, what is the approximate difference in the number of internet users between Karnataka and the state with the lowest number of internet users, which is 5 million?

  1. 10 million

  2. 15 million

  3. 20 million

  4. 25 million
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

To calculate the approximate difference in the number of internet users, we can subtract the number of internet users in the state with the lowest number of internet users from that of Karnataka. 25 million - 5 million = 20 million.

  1. 96%

  2. 97%

  3. 98%

  4. 99%
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

Since the pie chart represents the entire road network in India, the percentage of other types of roads combined must be the remaining portion after subtracting the percentage of national highways. Therefore, 100% - 2% = 98%.

Multiple choice

A pie chart shows the distribution of population by age groups in the state of Tamil Nadu, India. If the pie chart indicates that the age group of 20-40 years accounts for 35% of the total population, what is the approximate population in this age group if the total population of Tamil Nadu is 72 million?

  1. 25 million

  2. 28 million

  3. 31 million

  4. 34 million
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

To calculate the approximate population in the age group of 20-40 years, we can use the proportion represented by the pie chart. 35% of 72 million is (35/100) * 72 million = 0.35 * 72 million = 25 million.

Multiple choice

A pie chart compares the number of mobile phone subscribers in different regions of India. If the pie chart indicates that the North-Eastern region has 10 million mobile phone subscribers, what is the approximate percentage of mobile phone subscribers in the North-Eastern region if the total number of mobile phone subscribers in India is 1.2 billion?

  1. 0.8%

  2. 1.2%

  3. 1.6%

  4. 2.0%
