Select the odd one out from the given alternatives. (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)

    B 248 - 506 Correct Answer Incorrect Answer
    C 109 - 228 Correct Answer Incorrect Answer
    D 148 - 316 Correct Answer Incorrect Answer

    Solution

    The logic followed here is: Second number = 2 X First number + 10 126 - 262 → 2 X 126 + 10 = 262 248 - 506 → 2 X 248 + 10 = 506 109 - 228 → 2 X 109 + 10 = 228 148 - 316 → 2 X 148 + 10 = 306 ≠ 316
