Home > Logic Tests > Logical Problems > Logical Problems Questions
The logic problems in this set present you with three true statements:
Fact 1, Fact 2, and Fact 3.
Then, you are given three more statements (labeled I, II, and III), and you must determine which of these, if any, is also a fact.
One or two of the statements could be true; all of the statements could be true; or none of the statements could be true.
Choose your answer based solely on the information given in the first three facts.
Fact 1: Islands are surrounded by water.
Fact 2: Maui is an island.
Fact 3: Maui was formed by a volcano.
If the first three statements are facts, which of the following statements must also be a fact?
I: Maui is surrounded by water.
II: All islands are formed by volcanoes.
III: All volcanoes are on islands.
Answer & Explanation:
Answer: Option A
Explanation:
Since Maui is an island and islands are surrounded by water,Maui must be surrounded by water.
There is not enough information to support statements II and III.
Fact 1: Robert has four vehicles.
Fact 2: Two of the vehicles are red.
Fact 3: One of the vehicles is a minivan.
If the first three statements are facts, which of the following statements must also be a fact?
I: Robert has a red minivan.
II: Robert has three cars.
III: Robert's favorite color is red.
Answer & Explanation:
Answer: Option D
Explanation:
There is not enough information to support any of the statements.
Robert is known to have a minvan, but it is not known which of his vehicles is red.
Robert may have a pickup or sport utility vehicle, so the second statement cannot be supported.
There is no way to know if Robert's favorite color is red (statement III).
