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.)

(13, 16, 21)

Answer 1

The logic follows here as is,

(i): 3rd number = 13 + (16 ÷ 2) = 13 + 8 = 21

(ii): 3rd number = 28 + (34 ÷ 2) = 28 + 17 = 45

Apply the logic on the options,

Option 1: (37,18, 46)

3rd number = 37 + (18 ÷ 2) = 37 + 9 = 46 (true)

Option 2: (72, 45, 27)

3rd number = 72 + (45 ÷ 2) = 72 + 22.5 = 94.5 (false)

Option 3: (64, 26, 90)

3rd number = 64 + (26 ÷ 2) = 64 + 13 = 77 (false)

Option 4: (35, 12, 59)

3rd number = 35 + (12 ÷ 2) = 35 + 6 = 41 (false)

Here, the logic applies only to option 1.

Hence, 'option 1' is correct.
