In Ahmedabad city on a BRTS road if permissible FSI is 4, total area of all floors that can be constructed in a plot of 1000 m² is
- A250 m²
- B1000 m²
- C4000 m²Correct
- D2000 m²
Solution
Concept
Total floor area calculation using FSI
Formula
Total area = FSI × plot area
Step-by-step solution
1. Floor Space Index (FSI) = Total area of all floors / Plot area. 2. Total area of all floors = Permissible FSI × Plot area = 4 × 1000 m². 3. Total area of all floors = 4000 m². Answer: C
Explanation
Permissible total floor area is calculated by multiplying the permissible FSI by the plot area. For a plot of 1000 m² with an FSI of 4, the allowable construction area is 4 times 1000 m², which equals 4000 m². Hence, 4000 m² is the maximum total floor area that can be constructed.
Why the other options are wrong
A) 250 m² is obtained by incorrectly dividing the plot area by FSI. B) 1000 m² corresponds to an FSI of 1 instead of 4. D) 2000 m² corresponds to an FSI of 2 instead of 4.
Shortcut
Total floor area = FSI × Plot Area (4 × 1000 = 4000 m²).
Common mistake
Dividing the plot area by FSI to get 250 m² instead of multiplying it to find total floor area.
Correct answer: C) 4000 m²
