Question

Select the correct option which satisfies the logic given below.

324 (35) 289     400 (27) 49     484 (?) 81
1. 29
2. 31
3. 33
4. 37

Answer 1

Correct Answer - Option 2 : 31

The logic followed here is,

Square root of the first number and second number then adding the both results i.e.,

I → \(\sqrt {324} \)  + \(\sqrt {289} \) = 18 + 17 = 35

II → \(\sqrt {400} \) + \(\sqrt {49} \) = 20 + 7 = 27

Similarly, III → \(\sqrt {484}\)  + \(\sqrt {81}\) = 22 + 9 = 31

Therefore, 31 is the correct answer.
