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 their constituent digits. E.g. 13 – Operations on 13 such as adding/subtracting/multiplying to 13 can be performed. Breaking down 13 into 1 and 3 and then performing mathematical operations on 1 and 3 is not allowed.)

Answer 1

The logic followed here is:

Logic: 1st number + 2nd number = 3rd number.

11 - 12 - 23

→ 11 + 12

→ 23 = 3rd number

And
4 - 45 - 49

→ 4 + 45

→ 49 = 3rd number.

Similarly,

Option 1

68 - 12 - 80

→ 68 + 12

→ 80 = 3rd number.

Hence , the correct answer is "Option 1".
