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:

1282 : 5 :: ____ : 6

1. 1280
2. 2387
3. 2385
4. 1282

Answer 1

Correct Answer - Option 2 : 2387

The logic followed is:-

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

Second number = 5

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

= (5 + 1)⁴ - 14

= 6⁴ - 14

= 1296 - 14

= 1282

Similarly,

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

Fourth number = 6

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

= (6 + 1)⁴ - 14

= 7⁴ - 14

= 2401 - 14

= 2387

So, 1282 : 5 :: 2387 : 6

Hence, the correct answer is "2387".
