(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.)
(15, 14, 13)
(12, 10, 8)
Show answer & explanation
Correct answer: C
Explanation
The correct answer is option 3 i.e. (15, 15, 15).
(15, 14, 13) → (15 + 13) ÷ 2 = 14
(12, 10, 8) → (12 + 8) ÷ 2 = 10
Similarly, (15, 15, 15) → (15 + 15) ÷ 2 = 15
