Yes, answer is 33. I have used the guess and check method to get it. Any better method to share?

u is number of small packets, so 70-u is number of big packets. Multiply each by their respective mass and equate according to the statement about 1020 more for big packets.

Hi everyone, currently I'm a Maths consultant in England and I was hoping someone on this group could help me out. I'm planning to visit Singapore and spend a week or two in a primary and secondary school observing maths lessons for my own professional development. I've contacted a few schools but I've had no responses from them so I thought maybe some of the teachers from this group would be able to assisst me? Would any of your schools allow me to observe and interview teachers and children? Thank you.

Mohi. I just did this but on an organised trip. It's a bit of a mess as the answer is usually go through the ministry and then the ministry says contact schools. Give Andy and email and see if he got any contact info for the school's we were at. I have some emails etc, but am in transit (at phuket airport at the moment) and won't be home until the 10th. Let me know if you come up blank and I'll give you the,ail addresses of a couple of the school's we went to. Jeremy

Thanks J Samuel Hannay. Ahh that is a mess! I've emailed tons of schools but not a single reply. I'll email Andy but I know how busy he is as he travels a lot! I know I'll see him for the conference on the 24th April so I'll have a word with him then and see what I can sort out. Hope everything is going well for you, have a safe flight back.
