 Q. Common Information Question: 3/4 The total number of medals won by India was at least what percentage of the total number of medals won by China?
 ✖ A. 31.12% ✖ B. 75.80% ✔ C. 62.24% ✖ D. 39.50% ✖ E. Cannot be determined

Solution:
Option(C) is correct

We will assume that all the silver medals won by "others" were won by China only.

Number of medals won by India:

$= \dfrac{N}{8} + \dfrac{9N}{50} +\dfrac{33N}{200}$

$=\dfrac{47N}{100}$

Number of medals won by China:

$=\dfrac{3N}{8} +\dfrac{3N}{20} +\dfrac{23N}{100}$

$=\dfrac{151N}{200}$

⇒ Number of medals won by India is at least:

$= \dfrac{94}{151}$

$= 62.24\%$ of the number of medals won by China.
