 Q. Common Information Question: 2/4 What was the ratio of the number of gold medals won by Singapore to the number of silver medals won by Jordon ?
 ✖ A. 21 : 31 ✖ B. 4 : 5 ✖ C. 31 : 33 ✔ D. 29 : 31 ✖ E. Cannot be determined

Solution:
Option(D) is correct

At the end of each event exactly one each of gold, silver and bronze medals were awarded hence the total number of gold or silver or bronze medals must be the same.

Let there be $N$ number each of gold, silver and bronze medals.

Number of gold medals won by Singapore:

$= \dfrac{29N}{200}$

Number of Silver medals won by Jordon:

$=\dfrac{31N}{200}$

Hence the required ratio is $29:31$
