这些题目相当国内小学什么水平？
撇开英文水平不说 想了解一下这些题目相当国内小学什么水平？
1. David had 2 bags of marbles. After he had sold 44 marbles from Bag X to his friend, the number of marbles in Bag Y was 5/7 of the number of marbles in Bag X. Given that there were 2/5 as many marbles in Bag Y as in Bag X originally, find the number of marbles in Bag X at first.
2. John read a book in 3 days. He read 35% of the total number of pages in the book on the 2nd day. The ratio of the total number of pages of book he read on the 1st and 2nd day to the number of pages he read on the 3rd day was 11:9. If he had read 75 more pages on the 3rd day than on the 1st day, how many pages of the book did he read on the 2nd day ？.
