Based on the case, what is the approximate percentage weight loss from 14 kg to 12.9 kg over a month?

• A. 3.5%
• B. 7.9%
• C. 12%
• D. 5%

Answer: (B)

Percent weight loss is measured relative to the starting weight. The person lost 1.1 kg (14 kg → 12.9 kg). So the percentage is (1.1 / 14) × 100 ≈ 7.86%, which rounds to about 7.9%. This makes sense because losing 1.1 kg from a 14 kg baseline is just under 8% of the starting weight. For context, 3.5% would be about 0.49 kg, 5% about 0.7 kg, and 12% about 1.68 kg, none of which match the actual 1.1 kg loss.
