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.)
(21, 63, 189) (19, 57, 171)
Show answer & explanation
Correct answer: B
Explanation
The correct answer is option 2 i.e. (23, 69, 207).
The logic used here is:
(21, 63, 189)
189 - 63 = 126
126 ÷ 6 = 21
(19, 57, 171)
171 - 57 = 114
114 ÷ 6 = 19
Similarly,
(23, 69, 207)
207 - 69 = 138
138 ÷ 6 = 23
Hence, option 2 is the correct answer.
