are red, and the rest are blue, then

are blue. Assuming that the total number of chips, both red and blue, is an integer, then the total number of chips must be an integer multiple of 7, which is to say that the total number of chips is

such that

is an integer. Therefore the original number of red chips is

and the number of blue chips is
