Correct Answer: 661
Solution :
Given:
391 : 626 :: 426 : ? :: 173 : 408
The difference between the first number and the second number is 235.
Here, 391 : 626→626 – 391 = 235
And, 173 : 408→408 – 173 = 235
Similarly, follow the same pattern for 426 –
⇒ ? – 426 = 235
⇒ ? = 235 + 426
⇒ ? = 661
So, 661 is the required number in the given set of numbers. Hence, the second option is correct.
