Question
Select the set in which the numbers are related in the
same way as are the numbers of the following set. (16, 24, 20) (42, 58, 50)Solution
The logic followed here is: In each set, the average of the 1st and 2nd number is the 3rd number. In (16, 24, 20), 1st number = 16, 2nd number = 24, 3rd number = (16 + 24)/2} = 20 In (42, 58, 50), 1st number = 42, 2nd number = 58, 3rd number = (42 + 58)/2} = 50 Checking the options: A) In (14, 26, 22), 1st number = 14, 2nd number = 26, 3rd number = (14 + 26)/ 2 = 20 β 22 B) In (30, 45, 35), 1st number = 30, 2nd number = 45, 3rd number = (30 + 45)/2} = 37.5 β 35 C) In (22, 38, 30), 1st number = 22, 2nd number = 38, 3rd number = (22 + 38)/2} = 30 D) In (15, 25, 24), 1st number = 15, 2nd number = 25, 3rd number = (15 + 25)/2} = 20 β 24
