Question : 6 of 199

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.
18 ∶ 306 ∶∶ 23 ∶ ?

Solution:

The logic here is:
Square of the first number - first number = second number.

18 : 306 → 18^2 - 18 = 306

Similarly,

23 : ? → 23^2- 23 = 506

Hence, the correct answer is "506".
