Question
Select the option in which the numbers are NOT related
in the same way as are the numbers of the following set. (22, 31, 45) (54, 75, 105)Solution
The logic followed here is as follows: Second number = [First number + (Third number ÷ 5) ] In (22, 31, 45) , = [22 + (45 ÷ 5) ] = [22 + 9] = 31 In (54, 75, 105) , = [54 + (105 ÷ 5) ] = [54 + 21] = 75 (45, 70, 125) , = [45+ (125 ÷ 5) ] = [45 + 25] = 70 (112, 130, 120) , = [112 + (120 ÷ 5) ] = [112 + 24] = 136 ≠130 (75, 95, 100) , = [75 + (100 ÷ 5) ] = [75 + 20] = 95 (44, 84, 200) , = [44 + (200 ÷ 5) ] = [44 + 40] = 84
