Olympiad Test: Analogy and Classification - 2 - Class 6 MCQ

The relationship between 7 and 14 is that 7 multiplied by 2 equals 14. Similarly, 9 multiplied by 2 equals 18, making Option B correct. 

If we add 20 to 8, it equals 28. Similarly, when 27 has 20 added to it (27 + 20), it equals 47.

34  to 12 as 3x4 =12
59  to 45  as 5x9 = 45

• Option B (151) is the only odd number, whereas the others (312, 432, 234) are even numbers.


• Even numbers end with 0, 2, 4, 6, or 8, while odd numbers end with 1, 3, 5, 7, or 9.

If we square 1, it equals 1^2 = 1. Similarly, when we square 5 , it equals 25, which isn't among the options.
However 1 cube is also 1 so now 
, 5^3 equals 125, which is Option B.

If we multiply 16 by 3.5, it equals 56. Similarly, when 32 is multiplied by 3.5, it equals 112, which is Option D.

All numbers are prime numbers except for Option A, 1003, which is not a prime number as it can be divided by 17 and 59.
