Candidate Selection Architecture for SURVEYOR (BS-17)
📋 1. Examination Scheme & Marking Blueprint
The competitive recruitment screening for SURVEYOR (BS-17) consists of a single-paper 100-mark Multiple Choice Question (MCQ) written examination evaluating Architectural Design, Quantitative Aptitude Test, English Language Comprehension, and General Knowledge. The assessment duration is standardized at 90 minutes. A strict qualifying benchmark of 50% aggregate marks is mandatory for merit consideration. Negative marking is applied at a rate of 0.25 marks deducted per incorrect response, requiring candidates to exercise disciplined accuracy during question selection. Top-merit qualifiers are shortlisted for panel interview scrutiny at a ratio of 1:5 against announced vacancies.
| Examination Subject / Question Type | Target Marks | Weightage | Cognitive Focus & Syllabus Benchmark |
|---|---|---|---|
| Architectural Design | 50 MCQs | 50% | Building Construction Standards, RCC Structural Design, Surveying & Leveling, Quantity Estimation & Site Safety Codes |
| Quantitative Aptitude Test | 20 MCQs | 20% | Arithmetic calculations, algebra, geometric reasoning, quantitative problem solving |

Step-by-Step Explanation & Concept Rationale
Increase over 3 years (1965 to 1968):
\(21.3 - 20.8 = 0.5\text{ units}\)
Annual rate of increase: \(\frac{0.5}{3} \approx 0.1667\text{ units per year}\)
Time span from 1965 to 2000: \(2000 - 1965 = 35\text{ years}\)
Total projected increase by 2000: \(35 \times 0.1667 \approx 5.83\text{ units}\)
Projected value in 2000: \(20.8 + 5.83 = 26.63\text{ units}\)
Converting this back to the scale of millions yields approximately 2.66 million, which rounds cleanly to 2.7 million.
