Solution

The correct option is D All of the above.
Even if we change the groupings of the numbers we are adding, the total will always be the same.

In this case, as we can see

When we add options , we get:

Option. a

Option b.

Option c.

Thus, it doesn't matter which 2 numbers we add first, addition of given 3 numbers will be similar.
In this case $60 + 30 + 50$ = $(50 + 30) + 60$ = $60 + (30 + 50) =$ $(60 + 30) + 50$
