Mgbe ahụ, chọpụta ọnụ ọgụgụ nile nke mkpụrụ osisi pine ndị agụ nkwọ riri: mkpụrụ osisi pine 400 * 2 = mkpụrụ osisi pine 800. Mgbe ahụ, wepụ ihe abụọ ahụ iji chọpụta ọnụ ọgụgụ mkpụrụ osisi pine ndị fọdụrụnụ: mkpụrụ osisi pine 2000 - mkpụrụ osisi pine 400 - mkpụrụ osisi pine 800 = mkpụrụ osisi pine 800. Kewaa nọmba ahụ site na 4 iji chọta ọnụ ọgụgụ a na-achịkọta maka ọkụ: 800 pinecones / 4 = 200 pinecones. Mgbe ahụ, wepụ nọmba ahụ n'isi nkwụ 800 ahụ iji chọta ngụkọta ha fọdụrụ n'ala: nkwụ 800 - nkwụ 200 = nkwụ 600. Azịza ikpeazụ ya bụ: 600. <eng> First find the number of pinecones eaten by reindeer: 20% * 2000 pinecones = 400 pine cones. Then find the total number of pinecones eaten by squirrels: 400 pine cones * 2 = 800 pine cones. Then subtract those two amounts to find the number of pinecones left: 2000 pinecones - 400 pine cones - 800 pine cones = 800 pinecones. Divide that number by 4 to find the number that are collected for fires: 800 pinecones / 4 = 200 pine cones. Then subtract that number from the 800 pinecones to find the total left on the ground: 800 pine cones - 200 pinecones = 600 pine cones. The final answer: 600.
