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.)
(6, 4, 8) (17, 6, 28)
Show answer & explanation
Correct answer: D
Explanation
The correct answer is option 4 i.e. (13, 5, 21).
(6, 4, 8) ⇒ (4 + 8) ÷ 2 ⇒ 12 ÷ 2 = 6
(17, 6, 28) ⇒ (6 + 28) ÷ 2 ⇒ 34 ÷ 2 = 17
Similarly, (13, 5, 21) ⇒ (5 + 21) ÷ 2 ⇒ 26 ÷ 2 = 13
