ya, 73600000/63500000 gives 1.15 thus it's a 15% increase. values aren't exact here

what were the numbers again for that question
You needed 12 out of the 25 negatives
forgot the numbers
we need to find someone who else the paper but it's unlikely
because not many people do ocr maths compared to edexcel maths
