Question : Directions: Select the set in which the numbers are related in the same way as the numbers of the given sets.
(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.)
(15, 23, 31)
(33, 41, 49)
Option 1: (21, 29, 43)
Option 2: (20, 28, 36)
Option 3: (20, 33, 28)
Option 4: (35, 43, 56)
Correct Answer: (20, 28, 36)
Solution :
Given:
(15, 23, 31); (33, 41, 49)
The pattern is as follows –
(15, 23, 31)→15 + 31 = 46; 2 × 23 = 46
(33, 41, 49)→49 + 33 = 82; 2 × 41 = 82
Let's check the options –
First option:
(21, 29, 43); 43 + 21 = 64; 2 × 29 = 58 ≠ 64
Second option:
(20, 28, 36); 36 + 20 = 56; 2 × 28 = 56
Third option:
(20, 33, 28); 28 + 20 = 48; 2 × 33 = 66 ≠ 48
Fourth option:
(35, 43, 56); 56 + 35 = 91; 2 × 43 = 86 ≠ 91
So, only the second option follows the same pattern as followed by the given set of numbers. Hence, the second option is correct.
