by three conclusions I, II and III. You have to take the given statements to be true even if they seem to be at variance with commonly known facts. Read all the conclusions and then decide which of the given conclusion definitely follows from the given statements, disregarding commonly known facts. Statements:Some Pen are Book.Some Pencil are Book.All Pencil are Colour.Conclusions:I. Some Colour are Pencil.II. Some Pen are Colour.III. Some Book are Colour.Solution
All Pencil are Colour (A) β conversion β Some Colour are Pencil (I). Hence conclusion I follows.
Some Pen are Book (I) + Some Book are Pencil (A) β No conclusion. Hence conclusion II does not follows.
Some Pencil are Book (I) β conversion β Some Book are Pencil (I) + All Pencil are Colour (I) β Some Book are Colour (I). Hence conclusion III follows.
