Question
Select the set in which the numbers are related in the same
way as are the numbers of the following set.(9, 11, 40) (15, 7, 176)Solution
The logic followed here is: In each set, the absolute difference between the square of the 1st and 2nd number is the 3rd number. i.e., in (A, B, C) : C = |B² - A²|
In (9, 11, 40) = |11² - 9²| = |121 - 81| = 40
In (15, 7, 176) = |15² - 7²| = |225 - 49| = 176
In option '1', (8, 10, 38) = |10² - 8²| = |100 - 64| = 36 ≠38
In option '2', (13, 5, 140) = |13² - 5²| = |169 - 25| = 144 ≠140
In option '3', (6, 4, 20) = |6² - 4²| = |36 - 16| = 20
In option '4', (12, 11, 26) = |12² - 11²| = |144 - 121| = 23 ≠26
