Question
Statement Only a few Mirrors are Shadows
No Shadow is a Reflection All Mirrors are Refractions Conclusion I. Some Mirrors are not Reflections II. Some Refractions are Shadows III. All Refractions can never be Reflections In each question below, there are some statements followed by three conclusions numbered 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 and then decide which of the given conclusions logically follows follow(s) from the given statements.Solution
Some Mirrors are Shadows (I) + No Shadow is a Reflection (E) → Some Mirrors are not Reflections (O). Hence conclusion I follows. Some Mirrors are Shadows (I) → Conversion → Some Shadows are Mirrors (I) + All Mirrors are Refractions (A) → Some Shadows are refractions (I) → Conversion → Some Refractions are Shadows (I). Hence conclusion II follows. Some Mirrors are Shadows (I) + No Shadow is a Reflection (E) → Some Mirrors are not Reflections (O). All Mirrors are Refractions (A) → Conversion → Some refractions are mirrors (I) + Some Mirrors are not Reflections (O) → Probable conclusion → All Refractions can never be Reflections (A). Hence conclusion III follows.
