Study the given pattern carefully and select the number that can replace the question mark (?) in it.
(5, 19, 4)
(1, 7, 4)
(6, ?, 1)
(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: C
Explanation
The correct answer is option 3 i.e. 19.
The logic used here is:
Second number = (First Number x 3 ) + Third Number
Given,
(5, 19, 4)
⇒ (5 x 3) + 4 = 15 + 4 = 19
(1, 7, 4)
⇒ (1 x 3) + 4 = 3 + 4 = 7
Similarly,
(6, ?, 1)
⇒ (6 x 3) + 1 = 19
Hence, the correct answer is 19.
