Ответ:
So we make a sum of what's going to equal 52 in small packets.
I found 4x13=52. 13 would be the number of packets
BUT!! Since it MUST be equal dark and milk and we have 28 and 26,
you would have to eliminate 1 pack because all 4 would be milk chocolate.
So that is only 12 packets.
4 per pack so that would be 2 dark and 2 milk per packet.
