NEET 2026 (Phase 1) · BiologyPrevious Year Question
The WBC count of a person’s blood sample is 8000/cu mm. How many eosinophils and lymphocytes would be in the same blood sample approximately?
- A.300 – 500/cu mm and 1200 – 1500/cu mm respectively
- B.160 – 240/cu mm and 1600 – 2000/cu mm respectively✓
- C.300 – 500/cu mm and 500 – 700/cu mm respectively
- D.100 – 120/cu mm and 160 – 200/cu mm respectively
Correct Answer
(B) 160 – 240/cu mm and 1600 – 2000/cu mm respectively
Solution & Explanation
Answer: (b) 160 – 240/cu mm and 1600 – 2000/cu mm respectively Solution: Eosinophils form 2-3 per cent of total WBCs, so 2-3% of 8000 = 160-240/cu mm. Lymphocytes form 20-25 per cent, so 20-25% of 8000 = 1600-2000/cu mm. These values match option B. NCERT: Ch 15, p.195, line 03 — "Lymphocytes (20-25 per cent) are of two major types"
