    Question

    Select the pair in which the numbers are related to each

    other in the same way as are the numbers in the given pairs. (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.) 14 : 29 21 : 43
    A 16:39 Correct Answer Incorrect Answer
    B 26:51 Correct Answer Incorrect Answer
    C 22:45 Correct Answer Incorrect Answer
    D 19:36 Correct Answer Incorrect Answer

    Solution

    The logic followed here is as follows: For each number pair, 'A:B': B = A X 2 + 1 For '14:29': = 14 X 2 + 1 = 28 + 1= 29 For '21 : 43': = 21 X 2 + 1 = 42 + 1 = 43 In option '1', '16:39': = 16 X 2 + 1 = 32 + 1 = 33 ≠ 39 In option '2', '26:51': = 26 X 2 + 1 = 52 + 1 = 53 ≠ 51 In option '3', '22:45': = 22 X 2 + 1 = 44 + 1 = 45 In option '4', '19:36': = 19 X 2 + 1 = 38 + 1 = 39 ≠ 36
