Sa'an nan kuma yi daidai wannan abu don itatuwan maple: 60 logs / maple * 3 maples = 180 logs. Kuma ku yi daidai da itacen goro: 100 logs / goro * 4 walnuts = 400 logs. A ƙarshe, ka ƙara adadin katako daga kowane irin itace don ka samu duka: katako 640 + katako 180 + katako 400 = katako 1220. Amsar ita ce 1220. <eng> First find the total number of pine logs by multiplying the number of trees by the number of logs per tree: 80 logs / pine * 8 pines = 640 logs. Then do the same thing for the maple trees: 60 logs / maple * 3 maples = 180 logs. And do the same thing for the walnut trees: 100 logs / walnut * 4 walnuts = 400 logs. Finally, add up the number of logs from each type of tree to find the total number: 640 logs + 180 logs + 400 logs = 1220 logs. So the answer is 1220.
