Question

Select the option in which the number-pair shares the same relationship, as shared by the following number-pair.

18 : 38

A. 51 : 83
B. 38 : 70
C. 46 : 68
D. 28 : 60

Answer 1

The number-pair that shares the same relationship as the given number-pair 18 : 38, where there is a difference of 20, is option B. 38 : 70.

Step-by-step explanation:

The correct answer is option B. 38 : 70.

To find the pattern in the given number-pair (18 : 38), we observe that the difference between the two numbers is 20 (38 - 18 = 20). We need to apply the same logic to find a number-pair with a similar relationship among the available options. By analyzing the options, we find:

• Option A (51 : 83), the difference is 32, not 20.
• Option B (38 : 70), the difference is indeed 20 (70 - 38 = 32), which is the same as our original pair.
• Option C (46 : 68), the difference is 22, not 20.
• Option D (28 : 60), the difference is 32, not 20.

Hence, the number-pair that shares the same relationship as the given number-pair 18 : 38 is found in option B.
