tolong nomor 25 bserta caranya

Jagung = 20 %
Kedelai = 15%
Ketela = 90°/360° × 100 = 25 %
Padi = 20 + 15 + 25 = 60 = 100 - 60 = 40 %

Jagung = 20/40 x 420 = 210 kuintal
Kedelai = 15/40 x 420 = 157,5 kuintal
Ketela = 25/40 x 420 = 262,5 kuintal
Padi = 420 kuintal

210 + 157,5 + 262,5 + 420 = 1050 kuintal
