Question

Grayson is playing a game in which the object is to obtain a 0 by adding the points scored during each round.

Round 1 Round 2 Round 3 Round 4 Round 5

4

7

1

-12

Based on the points he scored during the first 4 rounds, what score does Grayson need on the 5th round?

-24

-11

12

Answer 1

0. See explanation below.

Explanation:

Grayson is playing a game in which the objective is to obtain a zero, by adding together the points scored in each round.

For rounds 1 to 4,

4 + 7 + 1 + -12 = 12 - 12 = 0

The summation of points in the first four rounds already results to a zero.

Let us see if the addition of any of the three options for round 5 will still result in a zero!

0 + -24 = -24

0 + -11 = -11

0 + 12 = 12

So all the options here are wrong. The only option that would have been correct is 0.

Since 4 + 7 + 1 + -12 + 0 = 0

Maybe the complete question has 0 as the fourth option. Use that.
