Correct Answer: 14.28%


Solution : Average cost price of J and K $=\frac{700+900}{2}=800$
Average selling price of L and M $=\frac{600+800}{2}=700$
Difference = 800 – 700 = 100
Required percentage = $\frac{\text{Difference}}{\text{Average of L and M}}\times100$
= $\frac{100}{700}\times100$
= $14.28$%
Hence, the correct answer is 14.28%.
