Study the given pattern carefully and select the number that can replace the question mark (?) in it.
(6, 2, 34)
(1, 5, 13)
(9, 1, ?)
(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)
Show answer & explanation
Correct answer: A
Explanation
The correct answer is option 1 i.e. 25.
The logic used here is:
(1st number × 2nd number × 3) - 2 = 3rd number
(6, 2, 34)
(6 × 2 × 3) - 2 = 36 - 2 = 34
(1, 5, 13)
(1 × 5 × 3) - 2 = 15 - 2 = 13
Similarly,
(9, 1, ?)
(9 × 1 × 3) - 2 = 27 - 2 = 25
