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 /deleting /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. 9-44-218.
Logic Used : (First Number × 5) + 1= Second Number, (Second Number × 5) + 1 = Third Number
Except Option 1,
⇒9-44-218
= (9 × 5) + 1 = 45 + 1 = 46
= (44 × 5) + 1 = 220 + 1 = 221
Thus, 9-44-218 is odd one out.
Hence, 9-44-218 is the correct answer.
