He can make 10 bags per day, so he needs 40 / 10 = 4 days to fulfill the customer’s order. <hau> Tunanin: Wallace ya riga yana da jakunkuna 20 na naman kaza, saboda haka yana bukatar ya yi 60 - 20 = 40 jakunkuna. Zai iya yin jakunkuna 10 a kowace rana, don haka yana buƙatar 40 / 10 = kwanaki 4 don cika odar abokin ciniki.
