Select the set in which the numbers are NOT related in the same way as the numbers of the given 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)
(12, 21, 84)
Show answer & explanation
Correct answer: D
Explanation
The correct answer is option 4 i.e. (24, 18, 96).
The logic used here is:
(12, 21, 84)
21 ÷ 3 = 7
12 × 7 = 84
Option 1: (14, 21, 98)
21 ÷ 3 = 7
14 × 7 = 98
This follows the logic.
Option 2: (14, 18, 84)
18 ÷ 3 = 6
14 × 6 = 84
This follows the logic.
Option 3: (16, 15, 80)
15 ÷ 3 = 5
16 × 5 = 80
This follows the logic.
Option 4: (24, 18, 96)
18 ÷ 3 = 6
24 × 6 = 144
This does not follow the logic.
Hence, option 4 is the correct answer.
