Select the set in which the numbers are related in the same way as are the numbers of the given sets.
(NOTE: Operations should be performed on the whole numbers, without breaking down the numbers into its 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)
(12, 7, 1385)
(19, 15, 3484)
Show answer & explanation
Correct answer: C
Explanation
The correct answer is option 3 i.e. (21, 16, 5165).
The logic followed is:
Logic: First number3 - second number3 = third number
(12, 7, 1385) → 123 - 73 = 1728 - 343 = 1385
(19, 15, 3484) → 193 - 153 = 6859 - 3375 = 3484
Now, checking the options:
Option (1): (17, 15, 1550) → 173 - 153
= 4913 - 3375 = 1538 ≠ 1550
Option (2): (11, 7, 955) → 113 - 73
= 1331 - 343 = 988 ≠ 955
Option (3): (21, 16, 5165) → 213 - 163
= 9261 - 4096 = 5165 = 5165
Option (4): (16, 14, 1321) → 163 - 143
= 4096 - 2744 = 1352 ≠ 1321
Thus, (21, 16, 5165) follows the same logic as in the given sets.
Hence, (21, 16, 5165) is the correct answer.
