Kai and Jordan had 300 marbles altogether. Kai gave away 25% fewer marbles than Jordan. Jordan was left with 50% as many as the number of marbles he gave away. Kai had 75% of the total number of marbles the boy left in the end. How many marbles did Kai have in the end?
+118608 There is a word missing in this sentence and I don't know what it is ??
Can you proof it please.
"Kai had 75% of the total number of marbles the boy left in the end."
I thought it was probably
"Kai had 75% of the combined total that the boys had left at the end"
But doing this I ended up with John having the initial number of 186 and 6/29 of a marble.
No one has 6/29 of a marble so the question, as I interpreted it, is not correct.

ok I edited
+118608 Please do not put 'asap' or similar in your questions. It makes me less likely to answer. Your questions are not more important than anyone elses.

See if you can find a logic error.
J stands for the number or marbles Jordan has at the beginning.
| Given | Kept | Total | |
| Jordan | \(\frac{2J}{3}\) | \(\frac{1J}{3}\) | J |
| Kai | \(\frac{J}{2}\) | \(\frac{J}{9}\) | \(\frac{11J}{18}\) |
| Total | \(\frac{21J}{18}\) | \(\frac{8J}{18}\) | \(\frac{29J}{18}=300\\ J=186\frac{6}{29}\) |

Ok I found my error, it was the middle square
| Given | kept | total | |
| jordan | \(\frac{2J}{3}\) | J/3 | J |
| Kai | J/2 | J | 3J/2 |
| Total | 7J/6 | 4J/3 | 300 |
\(J+\frac{3J}{2}=300\\ \frac{5J}{2}=300\\ J=120\\ check\\ (7*120/6)+(4*120/3)=300\;\;correct\)
So Kai keeps 120 marbles (which is the total number that Jordan has in the beginning)
| given | kept | total | |
| Jordan | 80 | 40 | 120 |
| Kai | 60 | 120 | 180 |
| Total | 140 | 160 | 300 |
