Question 1 of 3

In unknown age category, the ratio of males (unknown age category) and females (unknown age category) to total unknown cases (unknown age category) is same as the ratio of males (All) and females (All) to the total (total confirmed covid positive cases). How many females were in the unknown age category (rounded to nearest integer)?

  1. A.

    120

  2. B.

    140

  3. C.

    110

  4. D.

    125

  5. E.

    130

Answer

D

Explanation

Female ratio = 62434117586≈0.53096\frac{62434}{117586} \approx 0.53096. Females in unknown age = 235×0.53096≈125235 \times 0.53096 \approx 125.
