Some fans are coolers (I) + All coolers are AC (A) ⟹ Some fans are AC (I) + No AC is a switch (E) ⟹ Some fans are not switches. (O). All coolers are AC (A) + No Ac is a switch (E) ⟹ No cooler is a switch (E) ⟹ Some switches are not coolers (O). All switches are invertors (A) ⟹ Conversion ⟹ Some invertors are switches (I) ⟹ [Probable conclusion] ⟹ All invertors may be switches (A).
By elimination method - By option 1, there is no relation between fan and switch, so we can’t draw negative conclusion. Hence it is eliminated. By option 2, No switch is invertor. So it is eliminated. By option 4, we can’t draw –ve conclusion between Fan and switches. Hence it is eliminated. By option 3, the conclusion can be drawn. Hence answer is 3.
