Option 1: 678
Option 2: 867
Option 3: 768
Option 4: 876
Correct Answer: 768
Solution :
Given:
423 : 657 :: 534 : ?
Here, the difference between the numbers of both pairs is 234.
Like, 423 : 657→657 – 423 = 234
Let's check the options –
First option:
678; 678 – 534 =144 ≠ 234
Second option:
867; 867 – 534 = 333 ≠ 234
Third option:
768; 768 – 534 = 234
Fourth option:
876; 876 – 534 = 342 ≠ 234
So, only the third option follows the same pattern as followed by the given pair. Hence, the third option is correct.
