Difficult Syllogism Solutions Answers

1. 5; Converted (c) + (b) gives: Some golds are not paints [I + E = O]. 
Hence I does not follow, (a) + (c) gives no conclusion. 
Hence II does not follow. 
III and IV do not follow from (b) and (c) respectively.

2. 1; Converted (b) + (a) gives: Some fruits are flowers... (A). On conversion, we get I. 
Hence I follows and IV does not. (A) + (c) gives no conclusion. 
Hence II does not follow. 
III does not follow from (a) and (c).

3. 5 

4. 5 

5. 4

6. 1; First statement, on conversion, gives II. 
I and III do not follow from the rules of syllogism but they are complementary pair. 
Hence either I or III follows. 
IV does not follow from the last statement.

7. 4; No machine is a fly + Some flies are colours = Some colours are not machines [E +1 = O*]. 
Hence I does not follow. 
II does not follow from the last statement. 
Some flies are colours + All colours are sweets = Some flies are sweets, which on conversion gives conclusion III. 
IV also does not follow.

8. 5; Combining the last two statements, we get Some cars are not lemons. 
Hence I does not follow. 
II and III do not follow from the given statements. 
As, Some cars may be lemons or something else, hence IV does not follow.

9. 3; 1st statement + 2nd statement gives: Some goats are diamonds. 
Hence III follows.
III + last statement gives: Some goats are not green. 
Hence I does not follow. 
Conversion of second statement gives II. 
IV does not follow because of the last two statements.

10. 2; No conclusion follows from the rules of syllogism. But II and IV make a complementary pair. 
Hence either II or IV follows.
