Question:
Fresh potatoes = 1000 kg, initial solids = 14%, final solids = 93%.
Loss in peeling = 7%.
Find product yield percent (integer).
Fresh potatoes = 1000 kg, initial solids = 14%, final solids = 93%.
Loss in peeling = 7%.

Correct Answer: 14
Solution and Explanation
Solids in fresh potatoes:
\[
1000 \times 0.14 = 140\ \text{kg}
\]
After peeling:
\[
1000 - 7% = 930\ \text{kg}
\]
Solids remain the same (140 kg).
Final product mass:
\[
M_f = \frac{140}{0.93} = 150.5\ \text{kg}
\]
Yield % relative to original 1000 kg:
\[
Y = \frac{150.5}{1000} \times 100 = 15.05%
\]
\[
\boxed{15}
\]
