Question

One column of numbers consists of 28, 42, and 14. When the digits of the numbers are added together, the result is 2 + 8 + 4 + 2 + 1 + 4 = 21, and when the digits of 21 are then added together, the end result is 2 + 1 = 3. If the same process is performed on the numbers in a second column, what can be concluded?

A. If the end result from the second column is also 3, then the sum of the numbers in the first column is not equal to the sum of the numbers in the second column.
B. If the end result from the second column is not 3, then the sum of the numbers in the first column is equal to the sum of the numbers in the second column.
C. If the end result from the second column is also 3, then the sum of the numbers in the first column is equal to the sum of the numbers in the second column.
D. If the end result from the second column is not 3, then the sum of the numbers in the first column is not equal to the sum of the numbers in the second column.

Answer 1

Pick d i athinks that could be the right one

Answer 2

Answer:

Option: D is the correct answer.

Step-by-step explanation:

We are given a operation on the first column of the numbers.

Now,  If the same process is performed on the numbers in a second column.

Than the conclusion that can be made is:

D. If the end result from the second column is not 3, then the sum of the numbers in the first column is not equal to the sum of the numbers in the second column.

Since if the sum of the terms in the second column is other than 3 than definitely the sum is not going to be equal because on adding the digits of equal numbers the sum must be equal.

(

Option: A is incorrect.

( since, sum of both columns numbers may be equal)

Option: B is incorrect.

( since, adding the digits of the same numbers will be same)

Option: C is incorrect.

( Let the sum of numbers of first column is 21 and that of second column is 12) )
