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)

(34, 23, 12)

(71, 37, 3)

Options:

(75, 50, 20)

(20, 65, 50)

(19, 55, 91)

(14, 12, 16)

Correct Answer:

(19, 55, 91)

Explanation:

(34, 23, 12)

The logic followed here is : same number is adding and subtracting

Ist number - 11 = second number and second number - 11 = IIIrd number

34 - 11 = 23  and 23 - 11 = 12

(71, 37, 3)

Ist number - 34  = second number and second number - 34 = IIIrd number

71 - 34 = 37 and 37 - 34 = 3

Therefore

Ist number + 36  = second number and second number + 36 = IIIrd number

19 + 36= 55  and 55 + 36 = 91
