In the following question, select the related number pair from the given alternatives.
59:68::?:?
- A119:123
- B101:110
- C121:127
- D109:113
Solution & Step-by-step Explanation
Let's analyze the relationship between the first pair:
59→68
Add the sum of the digits of the first number to itself:
5+9=14
59+14=73
=68
Let's look at the difference:
68−59=9
Now let's check the options for a difference of 9:
Option A: 123−119=4
Option B: 110−101=9
Option C: 127−121=6
Option D: 113−109=4
Since the difference between 101 and 110 is exactly 9, it follows the same logic.
