Comments

By this we can't say some walls are fans 

In this all walls are fans and some fans are walls

---

here 'some' - can be any( not all. or  all) numbe but at least one. 

see this- 

---

based on statements we draw venn diagrams na some fans are walls could be draw even as above na

---

And in this type of question, try to find contradiction point.

---

for that point i tried to draw it as all walls are fans we are not known whether all or some walls are fans so i think none are true

---

no , first one is true - because in your diagrma - "all walls are fan is equivalent to say some walls are fan"  because some means- at least one or not all or all.
