Great compilation!

One note.

I think the line
> GCD(a,b) * LCM(a,b) = a*b e.g. GCD(12,15)*(12,15) = 12*15 = 180

should read

GCD(a,b) * LCM(a,b) = a*b e.g. GCD(12,15)* LCM(12,15) = 3*60 = 180

Or am I missing something.

BTW had the same question as anujairaj770

about

> BEWARE
> • In questions that ask for calculating total costs with fixed costs for first print / tkt / etc and variable
> for others, in final answer do not forget to include the first pic / tkt etc

Would be nice if you could write out these words in your doc or just add the explanation given above.

Thanks
