Weightage: what the paper actually did

Body Fluids and Circulation carried 2 questions in the NEET 2026 paper. One paper is a data point, not a destiny: NTA moves weight between chapters every cycle, which is why the weightage tables deserve care. The stable facts are the paper's shape: 180 questions, 720 marks, +4 right, −1 wrong.

Question 1 · NEET 2026

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?
  1. A.300 - 500/cu mm and 1200 - 1500/cu mm respectively
  2. B.160 - 240/cu mm and 1600 - 2000/cu mm respectively
  3. C.300 - 500/cu mm and 500 - 700/cu mm respectively
  4. D.100 - 120/cu mm and 160 - 200/cu mm respectively
Answer and explanation

Answer: B

Eosinophils make up roughly 2-3% of total WBCs, so in 8000/cu mm that is about 160-240/cu mm. Lymphocytes make up about 20-25%, giving about 1600-2000/cu mm. Only option 2 provides both correct ranges.
