(46-50) :
i) All kites are stars → Universal Affirmative (A – type).
(ii) Some cones are triangles →Particular Affirmative (I-type)
(iii) No star is a cone → Universal Negative (E-type)
(iv) Some stars are not cones →Particular Negative (O-type)
All kites are stars.
No star is a cone
A + E ⇒ E-type of Conclusion.
“No kite is a cone.”
No kite is a cone
Some cones are triangles
E + I ⇒ O1 - type of Conclusion
“Some triangles are not kites.”
No star is a cone.
Some cones are triangles
E + I ⇒ O1 - type of Conclusion“Some triangles are not stars.”
Some (not all) triangles are notstars. Therefore, there is somepossibility that some stars aretriangles.
“Some triangles are not stars”
→ Its Venn diagram would be :

It implies that some trianglesare stars and also all stars triangles.
