 * one at $2 \shillings 5 \oldpence$ per pound,
 * and the other, a better quality, at $3 \shillings 4 \oldpence$ per pound.
 * He mixes together some of each, which he proposes to sell at $3 \shillings 7 \oldpence$ a pound,
 * and so make a profit of $25$ per cent on the cost.


 * How many pounds of each kind must he use to make a mixture of $100$ pounds weight?
