Direction: In each of the question below are Four statements following by Four conclusions numbered I, II, II and IV. You have to take the Four given statements to be true even if they seem to be at variance with commonly known facts and then decide which of the given conclusion logically follows from the two statements disregarding commonly known fact.
-
Statement:
Some days are nights. Some nights are weeks. Some weeks are months. All months are years.
Conclusions:
I. Some years are nights.
II. Some years are days.
III. Some months are nights.
IV. Some years are weeks.
-
- Only I, II and III follow
- Only I, III and IV follow
- Only II, III and IV follow
- All follow
- None of these
Correct Option: B
Some nights are weeks + All weeks are months = I + A = I = Some nights are month → conversion → Some months are nights (I) Hence III follows. = Some nights are month + All months are years = I + A = I Some nights are year → conversion → Some years are nights (I) Hence I follows. All weeks are months + All months are years = A + A = A = All weeks are years → conversion → Some years are weeks (I) Hence IV follows. Some days are nights + Some nights are years = I + I = No conclusion Hence II does not follow.
