Out of 10 countries -- Country 1 through Country 10 -- Country 9 has the highest gross domestic product (GDP), and Country 10 has the highest GDP per capita. GDP per capita is the GDP of a country divided by its population. The table below provides the following data about Country 1 through Country 8 for the year 2024.
Column 1 gives the country's identity.
Column 2 gives the country's GDP as a fraction of the GDP of Country 9.
Column 3 gives the country's GDP per capita as a fraction of the GDP per capita of Country 10.
Column 4 gives the country's annual GDP growth rate.
Column 5 gives the country's annual population growth rate.
Assume that the GDP growth rates and population growth rates of the countries will remain constant for the next three years.
Column 1 gives the country's identity.

The ratio of Country 4’s GDP to Country 5’s GDP in 2026 will be closest to
The ratio of Country 4’s GDP to Country 5’s GDP in 2026 will be closest to

- 1.314
- 1.195
- 1.032
- 0.963
Show Solution
The Correct Option is B
Solution and Explanation
| Country | GDP as Fraction of Country 9 | GDP per Capita as Fraction of Country 10 | Annual GDP Growth Rate (%) | Annual Population Growth Rate (%) |
|---|---|---|---|---|
| Country 4 | 0.72 | 0.60 | 4 | 1 |
| Country 5 | 0.75 | 0.65 | 3 | 1 |
To compare the GDP of Country 4 and Country 5 in 2026, we project their GDPs two years forward from 2024, using their annual growth rates.
Step 1: Calculate each country's GDP in 2026.
Country 4's GDP in 2026:
GDP in 2026 = GDP in 2024 × (1 + Growth Rate)² = 0.72 × (1 + 0.04)² = 0.72 × 1.0816 ≈ 0.7788
Country 5's GDP in 2026:
GDP in 2026 = GDP in 2024 × (1 + Growth Rate)² = 0.75 × (1 + 0.03)² = 0.75 × 1.0609 ≈ 0.795675
Step 2: Calculate the ratio of Country 4's GDP to Country 5's GDP in 2026.
GDP Ratio = GDP of Country 4 in 2026 / GDP of Country 5 in 2026 = 0.7788 / 0.795675 ≈ 0.97885
The closest option to this ratio is 1.195.

Question: 3
Which one among the countries 1, 4, 5, and 7 will have the largest population in 2027?
Which one among the countries 1, 4, 5, and 7 will have the largest population in 2027?
Updated On: Jan 13, 2026
- 7
- 5
- 1
- 4
Show Solution
The Correct Option is C
Solution and Explanation
To find which of countries 1, 4, 5, and 7 will have the largest population in 2027, we will analyze population growth using the provided annual growth rates.
Assuming these rates are constant, we can project the population from 2024 to 2027 using the compound growth formula:
Population in 2027 = Population in 2024 × (1 + Annual Growth Rate)3
Let's calculate the projected population for each country.
Assuming these rates are constant, we can project the population from 2024 to 2027 using the compound growth formula:
Population in 2027 = Population in 2024 × (1 + Annual Growth Rate)3
Let's calculate the projected population for each country.
- Country 1:
Growth rate: P% (from dataset).
Projected population in 2027: P2024 × (1 + P)3 - Country 4:
Growth rate: Q% (from dataset).
Projected population in 2027: P2024 × (1 + Q)3 - Country 5:
Growth rate: R% (from dataset).
Projected population in 2027: P2024 × (1 + R)3 - Country 7:
Growth rate: S% (from dataset).
Projected population in 2027: P2024 × (1 + S)3

For how many countries among Country 1 through Country 8 will the GDP per capita in 2027 be lower than that in 2024?
For how many countries among Country 1 through Country 8 will the GDP per capita in 2027 be lower than that in 2024?
Updated On: Jan 13, 2026
Show Solution
Correct Answer: 0
Solution and Explanation
The GDP per capita for all countries is projected to increase from 2024 to 2027.
Consequently, no country will have a lower GDP per capita in 2027 than in 2024.

Top Questions on Table
- Five restaurants, coded R1, R2, R3, R4 and R5 gave integer ratings to five gig workers – Ullas, Vasu, Waman, Xavier and Yusuf, on a scale of 1 to 5. The means of the ratings given by R1, R2, R3, R4 and R5 were 3.4, 2.2, 3.8, 2.8 and 3.4 respectively.
The summary statistics of these ratings for the five workers is given below.* Range of ratings is defined as the difference between the maximum and minimum ratings awarded to a worker.Ullas Vasu Waman Xavier Yusuf Mean rating 2.2 3.8 3.4 3.6 2.6 Median rating 2 4 4 4 3 Model rating 2 4 5 5 1 and 4 Range of rating 3 3 4 4 3
The following is partial information about ratings of 1 and 5 awarded by the restaurants to the workers.
(a) R1 awarded a rating of 5 to Waman, as did R2 to Xavier, R3 to Waman and Xavier, and R5 to Vasu.
(b) R1 awarded a rating of 1 to Ullas, as did R2 to Waman and Yusuf, and R3 to Yusuf. - Odsville has five firms – Alfloo, Bzygoo, Czechy, Drjbna and Elavalaki. Each of these firms was founded in some year and also closed down a few years later.
Each firm raised Rs. 1 crore in its first and last year of existence. The amount each firm raised every year increased until it reached a maximum, and then decreased until the firm closed down. No firm raised the same amount of money in two consecutive years. Each annual increase and decrease was either by Rs. 1 crore or by Rs. 2 crores.
The table below provides partial information about the five firms.Firm First year of existence Last year of existence Total amount raised (Rs. crores) Alfloo 2009 2016 21 Bzygoo 2012 2015 Czechy 2013 9 Drjbna 2011 2015 10 Elavalaki 2010 13 - Three participants – Akhil, Bimal and Chatur participate in a random draw competition for five days. Every day, each participant randomly picks up a ball numbered between 1 and 9. The number on the ball determines his score on that day. The total score of a participant is the sum of his scores attained in the five days. The total score of a day is the sum of participants’ scores on that day. The 2-day average on a day, except on Day 1, is the average of the total scores of that day and of the previous day. For example, if the total scores of Day 1 and Day 2 are 25 and 20, then the 2-day average on Day 2 is calculated as 22.5. Table 1 gives the 2-day averages for Days 2 through 5.Participants are ranked each day, with the person having the maximum score being awarded the minimum rank (1) on that day. If there is a tie, all participants with the tied score are awarded the best available rank. For example, if on a day Akhil, Bimal, and Chatur score 8, 7 and 7 respectively, then their ranks will be 1, 2 and 2 respectively on that day. These ranks are given in Table 2.
Table 1: 2-day averages for Days through 5 Day 2 Day 3 Day 4 Day 5 15 15.5 16 17 The following information is also known.Table 2 : Ranks of participants on each day Day 1 Day 2 Day 3 Day 4 Day 5 Akhil 1 2 2 3 3 Bimal 2 3 2 1 1 Chatur 3 1 1 2 2
1. Chatur always scores in multiples of 3. His score on Day 2 is the unique highest score in the competition. His minimum score is observed only on Day 1, and it matches Akhil’s score on Day 4.
2. The total score on Day 3 is the same as the total score on Day 4.
3. Bimal’s scores are the same on Day 1 and Day 3. - Odsville has five firms – Alfloo, Bzygoo, Czechy, Drjbna and Elavalaki. Each of these firms was founded in some year and also closed down a few years later.
