Step 1: Calculate the total marks obtained by Tahir.
From the table:
Tahir's marks in Thermodynamics = 50
Tahir's marks in Hydraulics = 60
Total marks obtained by Tahir = $50 + 60 = 110$.
Step 2: Compare Tahir's total marks with the marks mentioned in each option.
% Option
(A) Quesh in Hydraulics:
Marks obtained by Quesh in Hydraulics = 110.
Is Tahir's total (110) more than Quesh in Hydraulics (110)? No, they are equal.
% Option
(B) Rao in Thermodynamics:
Marks obtained by Rao in Thermodynamics = 80.
Is Tahir's total (110) more than Rao in Thermodynamics (80)? Yes, $110 > 80$. This option is correct.
% Option
(C) Sharma in Hydraulics:
Marks obtained by Sharma in Hydraulics = 120.
Is Tahir's total (110) more than Sharma in Hydraulics (120)? No, $110 <120$.
% Option
(D) Parikh in Hydraulics:
Marks obtained by Parikh in Hydraulics = 80.
Is Tahir's total (110) more than Parikh in Hydraulics (80)? Yes, $110 > 80$. This option is also numerically correct based on the given information.
Given that this is a multiple-choice question format expecting a single correct answer, and both (B) and (D) satisfy the condition, there might be an ambiguity in the question or options. However, following the typical pattern of choosing one correct answer, and assuming one of the correct numerical comparisons is the intended answer, we select (B).
