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)

Answer 1

Given:

(5, 19, 4)

(1, 7, 4)

(6, ?, 1)

Logic: 'Row wise'

First row → Second no. = [(First no.) × 3 + Third no.]

First row (5, 19, 4) →

⇒ [(5 × 3) + 4]

⇒ (15 + 4) = 19

Second row (1, 7, 4) →

⇒ [(1 × 3) + 4]

⇒ (3 + 4) = 7

Similarly, for the third row (6, ?, 1):

⇒ [(6 × 3) + 1]

⇒ (18 + 1) = 19

Here, the question mark is replaced by '19'.

Hence, the correct answer is "Option (3)".
