Question : Directions: Select the set in which the numbers are related similarly to the numbers of the following set.
(NOTE: Operations should be performed on the whole numbers, without breaking down the numbers into their constituent digits. E.g. 13 - operations on 13 such as adding/subtracting/multiplying etc. to 13 can be performed. Breaking down 13 into 1 and 3 and then performing mathematical operations on 1 and 3 is not allowed.)
(85, 24, 133)
(97, 36, 145)
Option 1: (79, 18, 127)
Option 2: (71, 15, 124)
Option 3: (86, 23, 135)
Option 4: (67, 12, 111)
Correct Answer: (79, 18, 127)
Solution :
Given:
(85, 24, 133); (97, 36, 145)
In the given sets, subtract the first number by 61, to obtain the second number and add the second number to 109 to obtain the third number.
(85, 24, 133)→85 – 61 = 24; 24 + 109 = 133
(97, 36, 145)→97 – 61 = 36; 36 + 109 = 145
Now, let's check the options –
First option:
(79, 18, 127)→79 – 61 = 18; 18 + 109 = 127
Second option:
(71, 15, 124)→71 – 61 = 10
≠
15
; 15 + 109 = 124
Third option:
(86, 23, 135)→86 – 61 = 25
≠
23
; 23 + 109 = 132
≠
135
Fourth option:
(67, 12, 111)→67 – 61 = 6
≠
12
; 12 + 109 = 121
≠
111
So, only the first option follows the pattern of the given sets. Hence, the first option is correct.
