Question

Select the option that is related to the fourth number in the same way as the first number is related to the second number.

611 : 4 : : ? : 5

1. 1228
2. 1822
3. 1282
4. 2128

Answer 1

Correct Answer - Option 3 : 1282

The logic followed is:-

(Second number + 1)⁴ - 14 = First number.

First number = 611;

Second number = 4;

Applying the logic:-

(4 + 1)⁴ - 14

= 5⁴ - 14 

= 625 - 14

= 611

Similarly, 

Third number = ?

Fourth number = 5

Applying the logic:-

(Fourth number + 1)⁴ - 14 = Third number

(5 + 1)⁴ - 14

= 6⁴ - 14

= 1296 - 14

= 1282.

Hence, the correct answer is "1282".
