Question
Four number pairs have been given, out of which three
are alike in some manner and one is different. Select the one that is different.ÂSolution
The pattern followed here is: The second number is obtained by subtracting the square of the 2nd digit of the 1st number and the square of the 1st digit of the 1st number. (47, 33) = (7)² - (4)² = 49 - 16 = 33 (36, 27) = (6)² - (3)² = 36 - 9 = 27 (26, 32) = (6)² - (2)² = 36 - 4 = 32 (56, 15) = (6)² - (5)² = 36 - 25 = 11
