w₁ = 30 kg → menyusut 1,3%
w₁' = 30 - (30 × 1,3%)
w₁' = 29,61 kg
w₂ = 45 kg → menyusut 1,5%
w₂' = 45 - (45 × 1,5%)
w₂' = 44,33 kg
Tot. berat awal = 30 + 45 = 75 kg
Tot. berat akhir = 29,61 + 44,33
Tot. berat akhir = 73,94 kg
= (75 - 73,94)/75 × 100%
= 1,41%
Jawaban:

Penjelasan dengan langkah-langkah:
P1 = 1,3% × 30 = 0,39 kg
P2 = 1,5% × 45 = 0,675 kg
P1 + P2 = 0,39 + 0,675 = 1,065 kg
