The trader bought 100 oranges at 5 for N1.20, 20 oranges got spoilt and the remaining was sold at 4 for N1.50. Find the percentage gain or loss.
A. \(30 \%\) gain B. \(25 \%\) gain C. \(30 \%\) loss D. \(25 \%\) loss
Correct Answer: B
Explanation
\(CP =\frac{100}{5} \times 1.2= A 24\) Since 20 oranges got spoilt out of the 100 , the remaining will be 80 oranges. \(SP =\frac{80}{4} \times 1.5 \times 30\) Gain \(= SP - CP\) Gain \(=30-24=\) A 6 Percentage Gain \(=\frac{\text { Gain }}{C P} \times 100 \%\) \(=\frac{6}{24} \times 100 \%=25 \% \quad\)
