    Question

    Select the set in which the numbers are related in the

    same way as are the numbers of the following sets. (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) (35, 12, 29)                      (23, 16, 31)
    A (21, 25, 29) Correct Answer Incorrect Answer
    B (33, 30, 27) Correct Answer Incorrect Answer
    C (18, 12, 21) Correct Answer Incorrect Answer
    D (19, 8, 23) Correct Answer Incorrect Answer

    Solution

    ATQ, Given Set 1 = (35,12,29) Perform an operation on the first two numbers (35 and 12) to get the third (29). 35 - 12 = 29 The rule is subtract the second number from the first to get the third. Given Set 2 = (23,16,31) Perform the same operation = 23−16 ≠ 31 Subtraction doesn't work. Let’s try another method = 23+16=31 The rule here is add the first and second numbers to get the third, On comparing the options we get  21+25 = 46 ≠ 29  33+30 = 63 ≠27  18+12=30≠21  19+8 = 23  Therefore options 4 is correct
