# Currency notes - Part 2

**Number Theory**Level pending

While purchasing a gift last Christmas, I paid a few 1000-rupee notes. The shopkeeper gave me some 50-rupee notes as balance. He mentioned that the Xmas discount was 20% on the tag price. The currency notes I gave him had consecutive serial numbers from A to B, and the ones he gave me had consecutive serial numbers from C to D.

I observed the following:

(i) A and B leave the same remainder when divided by 6.

(ii) C is the largest 6-digit multiple of 5 of the form 2987xx and D is the next odd multiple of 6.

What was the tag price of the gift?
