Two statements are given followed by two conclusions numbered I and II. Assuming the statements to be true, even if they seem to be at variance with commonly known facts, decide which of the conclusions logically follow (s) from the statements.
Statements:
Some gold are silver.
All gold are platinum.
Conclusions:
1. Some silver are platinum.
II. All platinum are gold.

From the given statement following Venn diagram can be drawn- 

Conclusion I: "Some silver are platinum."
Since some gold are silver (from Statement 1) and all gold are platinum (from Statement 2), it logically follows that the part of gold that is silver will also be part of platinum. Therefore, Conclusion I follows.

Conclusion II: "All platinum are gold."
This conclusion does not follow, as Statement 2 only says that all gold are platinum, not that all platinum are gold. Thus, Conclusion II does not follow.

Therefore, only Conclusion I follows.
