2. Conditional Statements




Conditional statement type questions are likely to include a series of statements relating to:

  • All or,
  • Some or,
  • If statement.

E.g. If A is B and some C is B then it makes sense that….

Here are questions that are illustrated in the video:

QUESTION 1

Assume that some actors are singers and all the singers are dancers.

It is true then that:

A: Some actors are dancers.

B: No singer is an actor

C: Either some actors are dancers or no singer is an actor

D: Neither some actors are dancers nor no singer is an actor

E: Some actors are dancers and no singer is an actor.

QUESTION 2

Assume that some dogs are bats and some bats are cats.

It is true then that:

A: Some dogs are cats.

B: Some cats are dogs.

C: Some dogs are cats or some cats are dogs

D: Neither some dogs are cats not some cats are dogs.

E: Some dogs are cats and some cats are dogs.

QUESTION 3

Assume that some whis are nuds, all tans are wols, and some wols are whis.

Therefore it makes sense that:

A: some tans are nuds

B: some whis are tans

C: all wols are tans

D: all nuds are wols

E: some tans may be nuds

QUESTION 4

Assume that some juls are proos, all uups are juls, some nuls are kuls and all proos are puis.

Therefore it makes sense that:

A: some uups are puis

B: some puis are juls

C: all uups are proos

D: some nuls are puis

E: all puis are proos

Conditional statement type questions are likely to include a series of statements relating to:

  • All or,
  • Some or,
  • If statement.

E.g. If A is B and some C is B then it makes sense that….

Here is the standard approach:

*Step 1 *

Highlight all unique key words, these are words that are not repeating:

Assume that some huys are knis , all jiks are suds , and some aws are huys .

These are: HUYS, KNIS, JIKS, SUDS and AWS

*Step 2 *

Draw Diagrams to help solve this puzzle:

  • As some huys are knis, draw two circles that intersect.
  • As all jiks are suds, there will be two circles, jiks will be in the bigger circle as all jiks are suds.

Finally some Huys are Aws, so again we have two circles that intersect.

*Step 3 *

Look at your drawing.

Evaluate from the options provided.

Which one is therefore correct? (There should be no doubt as to the correct answer)

Key Rules to remember:

  • If all A is B, it means that some B is A not, all be is A.
  • If some A is B, then it's true that some B is A.
  • Use Venn diagrams if available and if not, reason.
  • Note well the unique key words
  • Study the Venn Diagrams
