Verified By Collegedunia
The Correct Option is B
Solution and Explanation
Step 1: Calculate total Hydraulics marks for Quesh and Sharma.
Quesh = 110
Sharma = 120
$$ \text{Total} = 110 + 120 = 230 $$ Step 2: Calculate total Thermodynamics marks for Parikh and Rao.
Parikh = 130
Rao = 80
$$ \text{Total} = 130 + 80 = 210 $$ Step 3: Find the ratio.
$$ \text{Ratio} = \frac{230}{210} = \frac{23}{21} = 23:21 $$ Conclusion: $$ \boxed{\text{(B) 23:21}} $$
Quesh = 110
Sharma = 120
$$ \text{Total} = 110 + 120 = 230 $$ Step 2: Calculate total Thermodynamics marks for Parikh and Rao.
Parikh = 130
Rao = 80
$$ \text{Total} = 130 + 80 = 210 $$ Step 3: Find the ratio.
$$ \text{Ratio} = \frac{230}{210} = \frac{23}{21} = 23:21 $$ Conclusion: $$ \boxed{\text{(B) 23:21}} $$

- The table shows the marks of five engineering students in Thermodynamics and Hydraulics. What is the ratio between the total marks obtained by Parikh in Thermodynamics and Hydraulics together and the same by Tahir?
- If the marks obtained by Tahir in Thermodynamics were increased by 24% of the original marks, then what would be his new approximate percentage in Thermodynamics, when the maximum marks were 140?
- The table shows the marks of five engineering students in Thermodynamics and Hydraulics. The total marks obtained by Tahir in both subjects are more than the marks obtained by:
- Four reviewers (R1, R2, R3, R4) are in charge of reviewing products from companies A, B, C, and D. Each reviewer provides a rating between 1 and 5 for the products. Due to a technical glitch, the original ratings were deleted, and only the averages calculated for each product (A, B, C, D) and each reviewer (R1, R2, R3, R4) were saved. The data available is as follows:Tasks:
A B C D Average 3 4 4 ? 4 3 ? 5 ? 4 ? 3 3 ? 4 ? ? ? ? 4.25 4 4 4 4.25

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.
