Select the option that is related to the 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.
485 : 25 :: ? : 21 :: 401 : 23
Answer & explanation
Correct answer: option 2
485 : 25 :: ? : 21 :: 401 : 23
The logic followed here is :
(IInd number - 3)2 + 1 = ist number
AS
(25 - 3)2 + 1
= 222 + 1
= 484 + 1 = 485
And
401 : 23
(23 - 3)2 + 1
= 202 + 1
= 400 + 1 = 401
Similarly
? : 21
(21 - 3)2 + 1
= 182 + 1
= 324 + 1 = 325
