The two barrels of A and B have the same amount of gasoline. After using (1/3) of A and B, 40% of B is used up, then 8 kg is taken out of A and poured into B. At this time, the weight ratio of A and B between the two barrels of gasoline is 14:13. How many kilograms of gasoline are there?
甲乙两桶汽油同样多，甲桶用去(1/3)，乙桶用去40%后，甲桶再取出8千克倒入乙桶，这时甲乙两桶汽油重量之比14：13，原来各有汽油多少千克？
