IDAT - International Diagnostic and Admission Logical Reasoning Puzzles Questions and Answers 1

Question 1

Four runners, Ali, Ben, Chloe, and David, are in a race. Ben finishes after Ali but before Chloe. David finishes before Ali. Which of the following represents a possible finishing order from first to last?

Accepted Answer

David, Ali, Ben, Chloe

Answer

The clues establish a specific partial order. 'David finishes before Ali' means the order must start with D...A. 'Ben finishes after Ali but before Chloe' means the sequence A...B...C must exist. Combining these facts, David must be before Ali, who is before Ben, who is before Chloe. The only order that satisfies all conditions is David, Ali, Ben, Chloe.

Question 2

Observe the pattern and determine which number should come next in the sequence: 5, 7, 11, 19, 35, ___

Accepted Answer

67

Answer

The pattern involves doubling the difference between the previous two numbers. The differences are: 7-5=2; 11-7=4; 19-11=8; 35-19=16. The next difference should be 16 * 2 = 32. Therefore, the next number in the sequence is 35 + 32 = 67.

Question 3

In a group of shapes, one is different from the others. Which shape is the odd one out?

Accepted Answer

A shape with 8 sides and 7 corners.

Answer

The common characteristic among the first, second, and fourth options is that they are all regular polygons where the number of sides is equal to the number of corners (a square, a hexagon, and a pentagon). The third option describes an irregular shape where the number of sides (8) does not equal the number of corners (7), making it the odd one out.

Question 4

A key is to a lock as a password is to a ___?

Accepted Answer

Login

Answer

The analogy is based on the function of providing access. A physical key is used to operate a lock and gain access. Similarly, a digital password is used at a login prompt to gain access to a system, account, or website.

Question 5

Three boxes are labeled 'Apples', 'Oranges', and 'Apples and Oranges'. It is known that every box is mislabeled. You are allowed to pick only one fruit from one box to determine the correct labels for all three. Which box should you pick from?

Accepted Answer

The 'Apples and Oranges' box

Answer

You should pick from the box labeled 'Apples and Oranges'. Since you know it's mislabeled, it cannot contain both; it must contain either only apples or only oranges. If you pick an apple from it, you know this box is the 'Apples' box. Consequently, the box labeled 'Oranges' must be 'Apples and Oranges' (since it can't be 'Oranges' and can't be 'Apples'), and the box labeled 'Apples' must be 'Oranges'. The same logic applies if you pick an orange.
