According to Indian standards for healthy housing, the total openable window area in a habitable room should be at least what fraction of the floor area?
- A One-eighth ✓
- B One-tenth
- C One-twentieth
- D One-fourth
Correct answer: A. One-eighth
Explanation
Indian housing standards require that the openable window area equal at least one-eighth of the floor area of the room, ensuring adequate daylight and natural ventilation; at least half of this window area should open directly outdoors. One-fourth would be generous but exceeds the prescribed minimum, while one-tenth and one-twentieth fall short of the standard. This norm appears repeatedly in Community Medicine examinations under the section on housing and health.
