Answers:

1. 4 
2. 2 
3. 1 
4. 1 
5. 1

6. 3; 
All toys are chairs (A) + No chair is furniture (E) i.e. = A + E = E No toy is furniture.

Now, No toy is furniture (E) + Some furniture are paint (I) i.e., (E) + (I) ----> O i.e.– Some paints are
not toys. So, I and II do not follow but they form a complimentary I ---> E type pair. Therefore either conclusion I or conclusion II follow.

7. 2

Some eraser are markers (I) + All markers are pencils (A) ----> I + A = I i.e. ----> Some erasers are pencils ----> Conversion ----> Some pencils are erasers (I)

Therefore Conclusion II follows.
Now, all pens are erasers (A) + Some pencils are erasers (I) ----> A + I ----> No Conclusion. Therefore Conclusion I does not follow.

8. 5

All metals are woods (A) + All woods are plastics (A) = A + A = All metals are plastics. Now, All metals are plastics (A) + No plastic is a gas (E) ----> A + E = E ----> No Metal is a gas. Hence Conclusion I follow again, All woods are plastic (A) + No plastic is a gas (E) ----> A + E ----> No wood is a gas. Hence conclusion II
follows.

9. 2

All woods are plastic – Conversion – Some plastic are woods. hence conclusion I does not follow. Again, All metal are woods (A) + All woods are plastics (A) ----> A ----> All metals are plastics. Hence conclusion II
follows.

10. 2

All Laptop are gadgets (A) ----> Conversion ----> Some gadgets are Laptops ie. I type. So, All tablets are gadgets (A) + Some gadgets are Laptops (I) ----> A + I ----> No conclusion. Therefore I does not follow.
Now, All mobiles are tablet (A) + All tablets are gadgets (A) ----> A + A ----> All mobiles are gadgets (A). Therefore. Conclusion II follow.
