Elijah, Xavier and Cody had some balls. Xavier had 60% less balls than Elijah. Xavier had
58 of Cody's. After Elijah gave 72 balls to Xavier, he had
14 of what Xavier had. How many more balls did Cody have than Elijah in the end?

Total balls of Elijah and Xavier |
Before |
16x1 = 16 u |
25x1 = 25 u |
10x1 = 10 u |
35x1 = 35 u |

After |
16 u |
1x7 = 7 u |
4x7 = 28 u |
5x7 = 35 u |
Number of balls that Xavier had less than Elijah at first in percent
= 100% - 60%
= 40%
40% =
40100 =
25 Elijah : Xavier = 5 : 2
The number of balls that Xavier had at first is repeated. Make the number of balls that Xavier had at first the same. LCM of 2 and 5 is 10.
When Elijah gave 72 balls to Xavier, the total number of balls that Xavier and Elijah had at first and in the end remains the same. Make the total number of balls that Xavier and Elijah had the same. LCM of 35 and 5 is 35.
Number of balls that Elijah gave to Xavier
= 25 u - 7 u
= 18 u
18 u = 72
1 u = 72 ÷ 18 = 4
Number of balls that Cody had more than Elijah in the end
= 16 u - 7 u
= 9 u
= 9 x 4
= 36
Answer(s): 36
