A health researcher records the visits made to four clinics in one month, as shown in the table. In which clinic does the share of visits made mainly for stress-related symptoms match what studies reveal about medical visits?
| Clinic | Total visits | Visits mainly for stress-related symptoms |
|---|---|---|
| P | 400 | 160 |
| Q | 500 | 300 |
| R | 200 | 160 |
| S | 300 | 75 |
Answer & explanation
Correct answer: option 2
The correct answer is Option (2) → Clinic Q
Option (1) Clinic P — Incorrect. 160 of 400 visits is 40 per cent. That is well below the share studies report for medical visits made for stress-related symptoms.
Option (2) Clinic Q — Correct. 300 of 500 visits is 60 per cent. Studies reveal that sixty per cent of medical visits are mainly for stress-related symptoms, so Clinic Q matches.
Option (3) Clinic R — Incorrect. 160 of 200 visits is 80 per cent. This is higher than the sixty per cent found for medical visits, and above even the fifty to seventy per cent estimated for the role of stress in physical illness.
Option (4) Clinic S — Incorrect. 75 of 300 visits is 25 per cent. That is far below the sixty per cent share reported for stress-related medical visits.
NCERT (2026-27): “Stress and Health … “Researchers estimate that stress plays an important role in fifty to seventy per cent of all physical illnesses. Studies also reveal that sixty per cent of medical visits are primarily for stress-related symptoms.” |
