Select the option that is related to the sixth number in the same way as the first number is related to the second number and third number is related to fourth number.
27 : 841 :: 18 : 400 :: ? : 324
Answer & explanation
Correct answer: option 2
27 : 841 :: 18 : 400 :: ? : 324
The logic followed here is :
(Ist number+2)2 = IInd number
As
(27+ 2)2
= 292
= 841
And
18 : 400
(18 + 2)2
= 202
= 400
Similarly
? : 324
(A + 2)2 = 324
(A + 2)2 = 182
(A + 2) = 18
A = 18 - 2
A = 16
