I am a Primary 6 Student and have been reading your blog since P5. I would like to ask for your help in the 2 questions from Pei Hwa Presbyterian CA1 Math paper:


Paper2
Q18:
7 apples cost $4
9 oranges cost $11
James bought a total of 1000 apples and oranges for $999.
How many apples and how many oranges did he buy?

Q5:
297 digits are used to print the page numbers of a story book.
What is the number on the last page number of the story book?

Please help me as I have spent so much time trying to find the answers and still can't.

Thank you so much and happy new year.
