Question

Lymphocytes and eosinophils are types of white blood cells. A blood sample has about 10 times as many lymphocytes as eosinophils. If there are 2 x 10^2 eosinophils in the sample, about how many lymphocytes are there?

a) 20 x 10^2
b) 200 x 10^2
c) 2 x 10^3
d) 20 x 10^3

Answer 1

In a blood sample with 2 x 10^2 eosinophils, there would be approximately 20 x 10^2 lymphocytes.

Step-by-step explanation:

Lymphocytes and eosinophils are types of white blood cells. Lymphocytes are the second most common type of leukocyte, accounting for about 20-30% of all leukocytes. Eosinophils typically represent 2-4% of the total leukocyte count. In the blood sample, if there are 2 x 10^2 eosinophils, then there would be about 10 times as many lymphocytes, which would be 10 x 2 x 10^2 = 20 x 10^2 lymphocytes.
