Select the option in which the numbers share the same relationship as that shared by the given pairs of numbers. (NOTE: Operations should be performed on the whole numbers, without breaking down the numbers into its constituent digits. E.g. 13 тАУ Operations on 13 such as adding/subtracting/multiplying etc. to 13 can be performed. Breaking down 13 into 1 and 3 and then performing mathematical operations on 1 and 3 is not allowed.) 96, 12 184, 23

Identify the ratio or factor: the second number is the result of dividing the first by a constant. Here, 96/12 = 8 and 184/23 = 8. Find the option where Ratio = 8.
Identify the ratio or factor: the second number is the result of dividing the first by a constant. Here, 96/12 = 8 and 184/23 = 8. Find the option where Ratio = 8.
Analyze the given pairs
In the pair (96, 12), dividing 96 by 12 gives 8. In the pair (184, 23), dividing 184 by 23 also gives 8.
Test the options
We need an option (X, Y) such that X / Y = 8. A) 130/16 = 8.125. B) 144/18 = 8. C) 156/19 = 8.21. D) 180/20 = 9.
A: 130/16 results in 8.125, not 8. C: 156/19 results in approximately 8.21, not 8. D: 180/20 results in 9, not 8.
B is correct because the ratio of the first number to the second number in the given pairs is 8, and only 144 divided by 18 equals 8.
In number analogy questions, always check for basic arithmetic operations like division or multiplication first before moving to complex squares or cubes.
