Question
Statements : All Stars are planet All Satellite
are galaxy Some planets are satellite Conclusions : I . At least some galaxy are Satellite II. No Satellite is a star. Directions (1-5): Read both the conclusions and then decide which of the given conclusions logically follows from the given statements disregarding commonly known facts. Give answer— (1) if only conclusion I is true. (2) if only conclusion II is true. (3) if either conclusion I or conclusion II is true. (4) if neither conclusion I nor conclusion II is true (5) if both conclusions I and II are true.Solution
Alternate solution: All Satellite are galaxies (A)
Conversion
Some galaxies are stars(I). Hence conclusion I follows. All Stars are planets(A) + Some planets are satellites(I)
No conclusion. Hence conclusion II does not follow.
