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 ?

The total white‑blood‑cell (WBC) count in the sample is given as 8000 cells per cubic millimetre.

Eosinophils normally make up about 2 %–4 % of the total WBC population. Using the lower and upper limits of the typical percentage range:

$2\%\times 8000=160$
$4\%\times 8000=320$

Most textbooks quote a narrower clinical range of 2 %–3 % for eosinophils, which gives:

$3\%\times 8000=240$

Thus the expected eosinophil count is roughly **160 – 240 cells per cu mm**.

Lymphocytes typically constitute about 20 %–25 % of the total WBC count. Calculating the limits:

$20\%\times 8000=1600$
$25\%\times 8000=2000$

Therefore the lymphocyte count is approximately **1600 – 2000 cells per cu mm**.

Combining both results, the blood sample is expected to contain:

**160‑240 cells/cu mm eosinophils** and **1600‑2000 cells/cu mm lymphocytes**, which matches the provided correct option.
