Question
Select the option that is related to fourth number in
the same way as the first number is related to the second number and the fifth number is related to the sixth number. 580:24 :: ?: 27 :: 260:16Solution
The logic followed here is as follows: From the left end, Add 4 to the square of the second number to get the first number. 580:24 → 24² + 4 = 576 + 4 = 580. 260: 16 → 16² + 4 = 256 + 4 = 260. 733: 27 → 27² + 4 = 729 + 4 = 733.
