Difficulty: Easy
Correct Answer: 121
Explanation:
Introduction / Context:
This question involves expressing parts of a total in fractions and then comparing those parts. It is a clean application of linear relationships and fraction arithmetic, typical in quantitative reasoning sections.
Given Data / Assumptions:
Concept / Approach:
Form expressions for both scores, subtract them, and solve for T. The denominators are manageable (11 and 121), making exact manipulation easy and reliable.
Step-by-Step Solution:
H − N = (3T/11) − (24T/121).Common denominator 121: H − N = (33T − 24T)/121 = 9T/121.Set 9T/121 = 9 ⇒ T = 121.
Verification / Alternative check:
Compute H = 3*121/11 = 33; N = 24*121/121 = 24; difference = 9, as required.
Why Other Options Are Wrong:
99, 110, 132, and 143 do not yield a 9-run difference with the specified fractional structure.
Common Pitfalls:
Taking the second-highest as 3/11 of T instead of the remainder; arithmetic slips in converting 3/11 of 8/11 T.
Final Answer:
121
