The following table gives the marks obtained by six students in six different subjects in an examination. The maximum marks for each subject are given in the brackets. Answer the questions that follow.
What is the average of total marks obtained by Aman, Kartik, Mukesh and Lokesh, in all subjects?
Show Hint
- 493.75
- 553.75
- 523.25
- 463.25
The Correct Option is B
Solution and Explanation
The question asks for the average of the total marks obtained by four specific students: Aman, Kartik, Mukesh, and Lokesh, across all six subjects.
Step 2: Key Formula or Approach:
1. Calculate the total marks for each of the four students by summing their marks in all subjects.
2. Sum the total marks of these four students.
3. Divide the grand total by 4 to find the average.
Step 3: Detailed Explanation:
First, we calculate the total marks for each student:
Total marks for Aman:
\[ 95 (\text{Hindi}) + 65 (\text{English}) + 115 (\text{Math}) + 100 (\text{Economics}) + 125 (\text{Accountancy}) + 90 (\text{Geography}) = 590 \] Total marks for Kartik:
\[ 60 + 95 + 130 + 95 + 100 + 80 = 560 \] Total marks for Mukesh:
\[ 105 + 90 + 95 + 110 + 140 + 85 = 625 \] Total marks for Lokesh:
\[ 55 + 115 + 60 + 65 + 75 + 70 = 440 \] Next, we sum the totals for these four students:
\[ \text{Sum of totals} = 590 + 560 + 625 + 440 = 2215 \] Finally, we calculate the average:
\[ \text{Average} = \frac{2215}{4} = 553.75 \] Step 4: Final Answer:
The average of the total marks is 553.75.
What percentage is the total marks obtained by Lokesh and Sumit in Hindi, English and Maths of the total marks obtained by Aman and Kartik in Economy, Accountancy and Geography (correct to one decimal place)?
Show Hint
- 78.8%
- 62.4%
- 65.9%
- 73.1%
The Correct Option is A
Solution and Explanation
We need to calculate a percentage. The numerator is the sum of marks of Lokesh and Sumit in Hindi, English, and Maths. The denominator is the sum of marks of Aman and Kartik in Economics, Accountancy, and Geography.
Step 2: Key Formula or Approach:
\[ \text{Required Percentage} = \frac{\text{Total Marks (Lokesh & Sumit in H, E, M)}}{\text{Total Marks (Aman & Kartik in Eco, Acc, Geo)}} \times 100% \] Step 3: Detailed Explanation:
First, calculate the numerator value:
Marks for Lokesh in (Hindi + English + Maths): \( 55 + 115 + 60 = 230 \)
Marks for Sumit in (Hindi + English + Maths): \( 75 + 85 + 75 = 235 \)
\[ \text{Total for Numerator} = 230 + 235 = 465 \] Next, calculate the denominator value:
Marks for Aman in (Economy + Accountancy + Geography): \( 100 + 125 + 90 = 315 \)
Marks for Kartik in (Economy + Accountancy + Geography): \( 95 + 100 + 80 = 275 \)
\[ \text{Total for Denominator} = 315 + 275 = 590 \] Finally, calculate the percentage:
\[ \text{Percentage} = \frac{465}{590} \times 100% \] \[ \text{Percentage} \approx 0.78813 \times 100% \approx 78.8% \] Step 4: Final Answer:
The required percentage is 78.8%.
Find the ratio of total percentage marks obtained by Sumit and Sandhya in Hindi, English and Maths.
Show Hint
- 49 : 73
- 53 : 78
- 47 : 63
- 39 : 88
The Correct Option is C
Solution and Explanation
The question asks for the ratio of the percentage of marks obtained by Sumit to the percentage of marks obtained by Sandhya in the three subjects: Hindi, English, and Maths combined.
Step 2: Key Formula or Approach:
The ratio of percentages will be the same as the ratio of the total marks obtained by each student in the specified subjects, because the maximum marks (the denominator for the percentage calculation) are the same for both.
Ratio = (Total Marks of Sumit in H, E, M) : (Total Marks of Sandhya in H, E, M).
Step 3: Detailed Explanation:
First, calculate the total marks for Sumit in Hindi, English, and Maths:
\[ \text{Sumit's Marks} = 75 + 85 + 75 = 235 \] Next, calculate the total marks for Sandhya in Hindi, English, and Maths:
\[ \text{Sandhya's Marks} = 85 + 110 + 120 = 315 \] Now, find the ratio of their marks:
\[ \text{Ratio} = 235 : 315 \] To simplify the ratio, we find the greatest common divisor of 235 and 315. Both numbers are divisible by 5.
\[ \frac{235}{5} : \frac{315}{5} \] \[ 47 : 63 \] The ratio cannot be simplified further.
Step 4: Final Answer:
The ratio is 47 : 63.
What is the difference of the total marks obtained in all subjects by Sumit and Mukesh?
Show Hint
- 130
- 150
- 120
- 140
The Correct Option is D
Solution and Explanation
The question asks for the absolute difference between the total marks obtained by Sumit and the total marks obtained by Mukesh across all six subjects.
Step 2: Key Formula or Approach:
1. Calculate the total marks for Sumit.
2. Calculate the total marks for Mukesh.
3. Find the difference between the two totals.
Step 3: Detailed Explanation:
First, calculate the total marks for Sumit in all subjects:
\[ \text{Sumit's Total} = 75 + 85 + 75 + 80 + 95 + 75 = 485 \] Next, calculate the total marks for Mukesh in all subjects (this was also calculated in Q.17):
\[ \text{Mukesh's Total} = 105 + 90 + 95 + 110 + 140 + 85 = 625 \] Finally, find the difference between their total marks:
\[ \text{Difference} = \text{Mukesh's Total} - \text{Sumit's Total} \] \[ \text{Difference} = 625 - 485 = 140 \] Step 4: Final Answer:
The difference in the total marks is 140.

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
