UCAT/ UKCAT Question Analysis - Q6.3-6.5
All biscuits produced in a biscuit factory contain nuts, except those produced under the brand NoNut. Several biscuit brands produced in the factory contain seeds.
Answer YES if the conclusion follows and NO if it doesn't.
Q6.3 If a biscuit is picked randomly from the factory's stock and is found not to contain nuts, then it must be a NoNut biscuit.
Q6.4 If two biscuits of two different brands are picked randomly from the factory and both contain seeds, then one of them has to be a NoNut biscuit.
Q6.5 If a biscuit does not contain nuts, it must contain seeds.
Answer:
Q6.3 Yes
Q6.4 No
Q6.5 No
Explanation:
Q6.3 Given that NoNut is the only brand not to contain nuts, any biscuit with no nuts has to be a NoNut biscuit.
Q6.4 The text does not preclude more than one brand of nutty biscuits from containing seeds. As such, as long as there are more than two brands, there is no obligation for one of the bixcuits to be a NoNut.
Q6.5 Nothing points to the fact that NoNut biscuits contain seeds.
