Instructions

In each of the questions below are given three statements followed by four conclusions numbered I, II, III and IV. You have to take the given statements to be true even if they seem to be at variance from commonly known facts. Read all the conclusions and then decide which of the given conclusions logically follows from the given statements disregarding commonly known facts.

Question 38

# Statements:Some chairs are buildings. All buildings are cars. Some cars are trucks.Conclusions: I. Some trucks are chairs.II. Some chairs are cars.III. Some cars are buildingsIV. No truck is chair.

Solution

We can draw many scenarios that satisfy the statements using Venn diagrams and check for the validity of the conclusions. Conclusions II and III hold in every case. So, they are implied.

Irrespective of the diagram, conclusions I and IV are universally complimentary ie. one of the two always has to be implied but both can't be true at the same time. Hence we use "either" and "or".
