Correct Answer: Option 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 \(=\frac{\text { Gain }}{C P} \times 100 \%\) \(=\frac{6}{24} \times 100 \%=25 \% \quad\)
\(CP =\frac{100}{5} \times 1.2= A 24\)
