1. bruto=164 kg Tara=3% berapakah nettonya 2. bruto=240 kg Tara= 20% berapakah nettonya 3. netto=270 kg tara = 10% hitunglah brutonya 4. bruto=300 kg netto=270

1. Netto = bruto - (bruto×tara)
= 164 - (164×3/100)
= 164 - 4,92
= 159,08
2. Netto = 240 - (240 × 20/100)
= 240 - 48
= 192
3. Bruto = netto + (netto × tara)
= 270 + (270 × 10/100)
= 270 + 27
= 297
4. Tara = {(bruto - netto) ÷ bruto} × 100%
= {(300 - 270) ÷ 300} × 100%
= (30 ÷ 300) × 100%
= 0,1 × 100%
= 10%

5. Bruto = 240 + (240 × 20/100)
= 240 + 48
= 288
