Hi Jo,

This is the solution offered for your question.
I make use of algebra, which I am not sure if you are taught the topic in Primary 5.

If no, then this solution may be complicated for you to understand.

Do take a look and let me know if you have any questions

Hi Jo, I dont think I can simplify the first few parts on expressing the amount of sand in the boxes after each step.

For the last part, I actually made use of calculator to solve for the values A, B and C.
If you are not taught on that, you can alternatively use "substitution" to solve for the values, which will take up more steps.

Cheers

No problem.

I apologise for the multiple steps that made it complicated, however, the question set by your teacher actually made it so haha
