The WBC count of a person's blood sample is 80008000/cu.mm. How many eosinophils and lymphocytes would be in the same blood sample approximately ?

Options

  1. A300−500300 - 500/cu.mm and 1200−15001200 - 1500/cu.mm, respectively
  2. B160−240160 - 240/cu.mm and 1600−20001600 - 2000/cu.mm, respectively
  3. C300−500300 - 500/cu.mm and 500−700500 - 700/cu.mm, respectively
  4. D100−120100 - 120/cu.mm and 160−200160 - 200/cu.mm, respectively

Correct answer

B. 160−240160 - 240/cu.mm and 1600−20001600 - 2000/cu.mm, respectively

Step-by-step solution

Total WBC count = 80008000/cu.mm.

Eosinophils constitute 2−3%2 - 3\% of total WBCs.

Number of eosinophils = 2100×8000\dfrac{2}{100} \times 8000 to 3100×8000=160−240\dfrac{3}{100} \times 8000 = 160 - 240/cu.mm.

Lymphocytes constitute 20−25%20 - 25\% of total WBCs.

Number of lymphocytes = 20100×8000\dfrac{20}{100} \times 8000 to 25100×8000=1600−2000\dfrac{25}{100} \times 8000 = 1600 - 2000/cu.mm.

Answer: 160−240160 - 240/cu.mm and 1600−20001600 - 2000/cu.mm, respectively
