Verified By Collegedunia
The Correct Option is D
Solution and Explanation
Step 1: Calculate total marks obtained by Parikh.
Parikh's marks:
Thermodynamics = 130
Hydraulics = 80
$$ \text{Total for Parikh} = 130 + 80 = 210 $$ Step 2: Calculate total marks obtained by Tahir.
Tahir's marks:
Thermodynamics = 50
Hydraulics = 60
$$ \text{Total for Tahir} = 50 + 60 = 110 $$ Step 3: Find the ratio of their total marks.
$$ \text{Ratio} = \frac{210}{110} = \frac{21}{11} $$ Now compare with given options: % Option (A) 3:2 → $ \frac{3}{2} = 1.5 $
% Option (B) 4:3 → $ \frac{4}{3} \approx 1.33 $
% Option (C) 5:3 → $ \frac{5}{3} \approx 1.67 $
$ \frac{21}{11} \approx 1.909 $ — does not match any option
$$ \Rightarrow \text{Correct answer is } \boxed{\text{(D) None of these}} $$

- 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.
