A caterer is making 16 ham sandwiches and 10 turkey sandwiches .

Half of the ham sandwiches are on wheat bread. Means 8 are on wheat bread.

So, 8 are on non wheat bread.

Two of the remaining ham sandwiches are on white bread and the rest are on rye .

This means 2 are on white bread and 6 are on rye.

Four of the turkey sandwiches are on white . Means 6 are on others.

The rest are equally divided into wheat and rye breads. This gives that 3 are on wheat and 3 on rye.
