Question : 10 of 200

Marks: +1, -0

Select the option that is related to the third number in the same way as the second number is related to the first number.
8 : 46 :: 9 : ?

Solution:

Second number

= (\First \number)^2 - 18

= 8^2 - 18

= 64 - 18 = 46

Similarly,
Fourth number

= (\Third \number)^2 - 18

= 9^2 - 18

= 81 - 18

= 63

So,

8 : 46 :: 9 : 63

Hence, the correct answer is "63".
