  • C) Only conclusion II is true
  • D) Neither conclusion I nor II is true
  • E) Only conclusion I is true
Solution

Ans : (D)

No apartment is a hall (E) + Some halls are rooms (I) = E + I = O* = Some rooms are not apartments. Hence conclusion II does not follow. Now, Some flats are apartments (I) + No apartment is a hall (E) = I + E = O = Some flats are not halls (O) + Some halls are rooms (I) = O + I = No conclusion. Hence conclusion I does not follow.
