In which year is the difference between the percentage increase in per capita income and the percentage increase in population compared to the previous year the highest?
Show Hint
- 2016-17
- 2018-19
- 2017-18
- 2015-16
The Correct Option is B
Solution and Explanation
We need to calculate the percentage increase in population and the percentage increase in Per Capita Income (PCI) for each year compared to the previous year. Then, we find the difference between these two percentages for each year and identify the year with the highest difference.
Preliminary Calculations: To answer the questions efficiently, we first calculate the Per Capita Income (PCI) for each year. The formula for Per Capita Income is: \[ \text{Per Capita Income (PCI)} = \frac{\text{National Income}}{\text{Population}} \] The given National Income is in 'Rupees Crore' and the Population is in 'crore'. Therefore, the PCI will be in 'Rupees'.
PCI 2014-15: \( \frac{343837.5}{111.00} = 3097.64 \)
PCI 2015-16: \( \frac{391761.0}{112.50} = 3482.32 \)
PCI 2016-17: \( \frac{437334.0}{115.50} = 3786.44 \)
PCI 2017-18: \( \frac{494901.0}{117.75} = 4202.98 \)
PCI 2018-19: \( \frac{582808.5}{120.00} = 4856.74 \)
PCI 2019-20: \( \frac{650250.0}{122.25} = 5318.98 \)
These values will be used in the following solutions.
Step 2: Key Formula or Approach:
\[ \text{Percentage Increase} = \frac{\text{Current Year Value} - \text{Previous Year Value}}{\text{Previous Year Value}} \times 100% \] We will apply this formula to both Population and PCI for the years 2015-16 to 2019-20.
Step 3: Detailed Explanation:
Let's calculate the required values for each year.
For 2015-16:
% Inc. in Population = \( \frac{112.50 - 111.00}{111.00} \times 100 \approx 1.35% \)
% Inc. in PCI = \( \frac{3482.32 - 3097.64}{3097.64} \times 100 \approx 12.42% \)
Difference = 12.42% - 1.35% = 11.07%
For 2016-17:
% Inc. in Population = \( \frac{115.50 - 112.50}{112.50} \times 100 \approx 2.67% \)
% Inc. in PCI = \( \frac{3786.44 - 3482.32}{3482.32} \times 100 \approx 8.73% \)
Difference = 8.73% - 2.67% = 6.06%
For 2017-18:
% Inc. in Population = \( \frac{117.75 - 115.50}{115.50} \times 100 \approx 1.95% \)
% Inc. in PCI = \( \frac{4202.98 - 3786.44}{3786.44} \times 100 \approx 11.00% \)
Difference = 11.00% - 1.95% = 9.05%
For 2018-19:
% Inc. in Population = \( \frac{120.00 - 117.75}{117.75} \times 100 \approx 1.91% \)
% Inc. in PCI = \( \frac{4856.74 - 4202.98}{4202.98} \times 100 \approx 15.55% \)
Difference = 15.55% - 1.91% = 13.64%
For 2019-20:
% Inc. in Population = \( \frac{122.25 - 120.00}{120.00} \times 100 \approx 1.88% \)
% Inc. in PCI = \( \frac{5318.98 - 4856.74}{4856.74} \times 100 \approx 9.52% \)
Difference = 9.52% - 1.88% = 7.64%
Comparing the differences, the highest value is 13.64% in the year 2018-19.
Step 4: Final Answer:
The difference is highest in the year 2018-19.
In which year is the increase in per capita income compared to the previous year the lowest?
Show Hint
- 2019-20
- 2016-17
- 2015-16
- 2017-18
The Correct Option is B
Solution and Explanation
The question asks for the year with the smallest absolute increase (not percentage) in per capita income compared to the preceding year.
Step 2: Key Formula or Approach:
We need to calculate the difference in PCI between each year and the previous year.
\[ \text{Increase in PCI} = \text{PCI of Current Year} - \text{PCI of Previous Year} \] Step 3: Detailed Explanation:
Using the PCI values calculated previously:
Increase in 2015-16: \( 3482.32 - 3097.64 = 384.68 \)
Increase in 2016-17: \( 3786.44 - 3482.32 = 304.12 \)
Increase in 2017-18: \( 4202.98 - 3786.44 = 416.54 \)
Increase in 2018-19: \( 4856.74 - 4202.98 = 653.76 \)
Increase in 2019-20: \( 5318.98 - 4856.74 = 462.24 \)
Comparing the absolute increases, the lowest value is 304.12.
Step 4: Final Answer:
The lowest increase in per capita income occurred in the year 2016-17.
Which of the following years witnessed the highest increase in per capita income compared to the previous year?
Show Hint
- 2015-16
- 2016-17
- 2018-19
- 2017-18
The Correct Option is C
Solution and Explanation
This question asks for the year with the largest absolute increase in per capita income compared to the previous year.
Step 2: Key Formula or Approach:
We will use the absolute increase values calculated in the solution for the previous question.
\[ \text{Increase in PCI} = \text{PCI of Current Year} - \text{PCI of Previous Year} \] Step 3: Detailed Explanation:
Referring to the calculations from Question 10:
Increase in 2015-16: 384.68
Increase in 2016-17: 304.12
Increase in 2017-18: 416.54
Increase in 2018-19: 653.76
Increase in 2019-20: 462.24
By comparing these values, the highest increase is 653.76.
Step 4: Final Answer:
The highest increase in per capita income occurred in the year 2018-19.

Questions Asked in SRCC GBO exam
Read the given passage and answer the questions.
For those of us without access to outside green space, houseplants are a stylish and affordable way of getting a nature fix. Alongside looking nice, indoor plants actually have several other perks- the biggest benefit of which could be improving your mental health. And the good news is you don’t need to be a self-professed” plant parent” to experience these benefits either. One in eight UK households don’t have access to any kind of garden. Young people and those from minority ethnic backgrounds are among those least likely to have a garden. Not having access to nature can have a number of effects on our health. It’s been linked to symptoms of depression and anxiety, as well as other health conditions, such as asthma, cardiovascular disease, and poor immune function. For many of us, houseplants are an essential link to nature. While there’s not yet a robust body of research on the mental health benefits of houseplants specifically, plenty of studies have shown how beneficial green space and gardening are for mental health. For instance, one study found that people who garden daily have better wellbeing and lower stress levels compared to those who don’t. Gardening also reduces symptoms of depression and anxiety and increases positive emotions to the same extent as biking, walking and eating out. Many of these outcomes are likely to be true of houseplants too. A recent review of 42 studies demonstrates that even just being in the presence of indoor plants can improve mental and physical health. These experiments compared participants doing various activities in rooms with or without plants. The presence of plants saw better performances on cognitive tasks involving focus, sorting or memory recall, greater pain tolerance when holding hands in ice cold water, and lower levels of physiological stress. Interestingly, the aesthetic appearance of plants is important too, with separate research showing that people tend to react more positively to lush, green plants with rounded and denser foliage. But most of these studies are centred around the mere presence of plants. From research on the benefits of gardening, we can assume that caring for houseplants will bring out many more emotional benefits- such as pride, social connection, satisfaction, fascination, mental resilience in times of stress, and may even help you heal from past trauma.... Plants can remove pollutants such as carbon dioxide, nitrogen dioxide (from nearby traffic), fine particles (from dust) and volatile organic compounds (from air fresheners, cooking and cleaning). For people indoors for the majority of the day, indoor air quality is hugely important. High concentrations of carbon dioxide can reduce cognitive performance (such as concentration and memory recall) while prolonged exposure to other indoor pollutants can cause long-term health problems- ranging from minor eye or throat irritations to respiratory problems and cancer. But removing a meaningful quantity of indoor pollutants would require a lot of plants in a very bright room- something unrealistic for most people. If you do want to give it a try, plants with a high leaf area- such as an India rubber tree (Ficus elastic) or devil’s ivy (Epipremnum aureum) are your best bet- SRCC GBO - 2026
