Question
Read the given statements and conclusions carefully.
Assuming that the information given in the statements is true, even if it appears to be at variance with commonly known facts, decide which of the given conclusions logically follow(s) from the statements. Statements: Few Colour are Paint All Paint are Wall Some Paint are Room Conclusion: I. Some Colour are Room II. Some Wall are Colour III. All Room can be ColourSolution
Few Colour are Paint (I) + Some Paint are Room (I) → No conclusion. Hence conclusion I does not follow. Few Colour are Paint (I) + All Paint are Wall (A) → Some Colour are Wall (I) → Conversion → Some Wall are Colour (I). Hence conclusion II follows. Few Colour are Paint (I) + Some Paint are Room (I) → Probable conclusion → Some Colour are Room (I) → Probable conclusion → All Room can be Colour (A). Hence conclusion III follows.
cos A (sec A – cos A) (cot A + tan A) = ?
