Correct Answer: 14%


Solution : New selling price = INR 29 per kg
Old selling price = INR 25 per kg
Let the expenditure be 100 kg.
So, last months expenditure = 25 × 100
This months expenditure $=\frac{25 × 100}{29}=86.21$ kg
So, the Reduction percentage $=\frac{100-86.21}{100}×100=13.79 \approx14$%
Hence, the correct answer is 14%.
