Buns were being sold at three prices: one for a penny, two for a penny,
and three for a penny. Some children (there were as many boys as girls) were
given seven pennies to spend on these buns, each child to receive exactly the
same value in buns. Assuming that all buns remained whole, how many
buns, and of what types, did each child receive?
Answer:
There must have been three boys and three girls, each of whom received two buns at three for a penny and one bun at two for a penny, the cost of which would be exactly 7¢.
