42 is related to 21 following a certain logic. Following the same logic, 26 is related to 13. To which of the following is 68 related following the same logic? (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.)

Observe the constant ratio between the numbers: the second number is consistently half of the first number (n/2).
Observe the constant ratio between the numbers: the second number is consistently half of the first number (n/2).
Analyze the relationship between 42 and 21
Perform the division: 42 divided by 2 equals 21. The pattern is defined as x / 2 = y.
Verify the relationship for 26 and 13
Perform the division: 26 divided by 2 equals 13. This confirms the rule x / 2 = y is consistent.
Apply the rule to 68
Apply the established logic to the target number: 68 divided by 2 equals 34.
A: 30 is wrong because 68/2 is 34, not 30. B: 32 is wrong because 68/2 is 34, not 32. D: 36 is wrong because 68/2 is 34, not 36.
C is correct because the logic follows a constant division by 2, where 68 divided by 2 equals 34.
When dealing with small even numbers, always check for simple division or multiplication patterns first before looking for complex square or cube operations.
