Answer 2

Answer: There are 56 pairs of whole numbers having a sum of 110.

Step-by-step explanation:

Since we have given whole numbers and we want a sum of 110 .

Starting from 0 we have :

0+110=110

1+109=110

2+108=110

3+107=110

and goes on until repetition starts ..

i.e. 55+55=110

after this repetition gets started so, we stop there.

Starts counting form 0 to 55 , there are 56 pairs of whole numbers having a sum of 110.

Hence, there are 56 pairs of whole numbers having a sum of 110.
