So, the four sections collected a total of 420 x 4 = 1680 kilos. Hence, their target is to collect 1680 + 320 = 2000 kilos of the newspaper. The final answer: 2000. <ibo> N'ime otu izu, ngalaba nke ọ bụla chịkọtara akwụkwọ akụkọ dị kilogram 280 / 2 = 140. N'ihi ya, n'ime izu atọ, otu ngalaba chịkọtara kilogram 140 x 3 = 420.
