Question

In the following question, select the related number pair from the given alternatives.

144 : 400 :: ?

1. 256 : 591
2. 121 : 387
3. 225 : 471
4. 324 : 580

Answer 1

Correct Answer - Option 4 : 324 : 580

The logic follows here is:

400 - 144 = 256

Now, check which option satisfies this condition.

1) 256 : 591

591 - 256 = 335

2) 121 : 387 

387 - 121 = 266

3) 225 : 471

471 - 225 = 246

4) 324 : 580

580 - 324 = 256

Only, option 4) satisfies the above condition.

Hence, the correct answer is 324 : 580.
