Answer 2

The following three pairs of cards are 1) -3,-1. 2) -5,1. 3) -7,3.

Given,

The six number cards = -5 , -7 , -3 , -1 , 1 , 3.

To Find,

Arrange the cards into 3 pairs with the same total.

Solution,

We have given the Six number cards

=  -5 , -7 , -3 , -1 , 1 , 3.

We have to arrange it so that the total will be the same upon adding the two numbers.

So,

Let's find the First pair,

= -5 + 1

On adding, we get,

= -4.

Let's find the second pair,

= -7 + 3

On adding, we get,

= -4

Let's find the pair,

= -3 + (-1)

On adding, we get,

= -4.

Hence, all the chosen pairs have the same total.

The following three pairs of cards are 1) -3,-1. 2) -5,1. 3) -7,3.
