Study the given pattern carefully and select the number that can replace the question mark (?) in it.
(16, 4, 4)
(30, 5, 15)
(8, 2, ?)
(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)
Show answer & explanation
Correct answer: A
Explanation
The correct answer is option 1 i.e. 2.
The logic followed is:
Logic: First No. - (3 × Second No.) = Third No.
(16, 4, 4 )→
= 16 - (3 × 4) = 4
(30, 5, 15) →
= 30 - (3 × 5) = 15
So, (8, 2, ?) →
= 8 - (3 × 2) = 2
Thus, (8, 2, 2).
Hence, 2 is the correct answer.
