Syllogism solved examples ( Part I )

Example 1:

Statements: Some Trains are cars; All Cars are branches; All branches are nets; Some nets are                            dresses.

Conclusions: Some Dresses are Cars; Some Nets are Trains; Some Branches are Trains; Some                              Dresses are Trains.

Step 1: Diagram

 Step 2: Analyzing Conclusions

1 – Some Dresses are Cars – It does not follows – No Direct Connection between Cars and Dress

2 – Some Nets are Trains – It Follows (Check Concept 2)

3 – Some Branches are Trains – It Follows

4 – Some Dresses are Trains – It does not follows – No Direct connection between Dresses and                                                       Trains.

Example 2

Statements: All Stones are Hammers; No Hammer is Ring; Some rings are doors; All doors are                           windows

Conclusions : Some windows are stones; some windows are rings; No window is stone; Some                             rings are stones.

Conclusion 1 – Definitely false (No direct connection)

Conclusion 2 – Definitely True

Conclusion 3 – Definitely False (Check Concept 11)

Conclusion 4 – Definitely False (No direct Connection)

Now Check for Merging Concept. Because More than one statement is false. Conclusion 1 and 3 have same characters. One is positive and another is negative.

So the Answer is Conclusion 2 and Either Conclusion 1 or 3 follows

---

Example 3

Statements : All Pens are Clocks; Some Clocks are tyres; Some tyres are wheels; Some                                        wheels are buses.

Conclusions: Some Buses are tyres; Some wheels are clocks; Some wheels are pens;                                            Some Buses are Clocks.

Conclusion 1 – Definitely False (Refer Concept 2)

Conclusion 2 – Definitely False

Conclusion 3 – Definitely False

Conclusion 4 – Definitely False

Answer is NONE FOLLOWS

---

Example 4

Statements: All baskets are Marbles; Some marbles are sticks; No stick is garden

Conclusions: Some Gardens are baskets; Some Sticks are Baskets; No Garden is basket

Conclusion 1 – Definitely False (Concept 2)

Conclusion 2 – Definitely False (Concept 2)

Conclusion 3 – Definitely False (Concept 11)

Now we have to check for Merging Concept. We can merge Conclusion 1 and Conclusion 3.

Answer is Either 1 or 3 Follows
