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.) (84, 73, 157) (96, 88, 184)
(89, 62, 151)
In the given sets, the relationship between the numbers is as follows: 84 + 73 = 157 96 + 88 = 184 Let's check the options: 1. 89 + 62 = 151 2. 88 + 79 = 167 ≠ 191 3. 99 + 71 = 170 ≠ 160 4. 92 + 75 = 167 ≠ 147 Therefore, only option 1 follows the same pattern.
