料 combines 米 (rice) and 斗 (a measuring ladle or dipper), suggesting the act of measuring rice or grain. This measuring sense extended to apportioning fees and materials.
Picture a measuring ladle (斗) next to rice (米): you are measuring out rice to pay a fee or to gather materials for cooking.
For リョウ, imagine a landlord named Ryo measuring rice to collect the rent fee: Ryo -> リョウ, and the ladle measures the rice.
