(d)50\%
Answer
Answer (as printed): D
Explanation
Let the C.P. of each article be ₹ 100. Then, C.P. of 16 articles $=₹(100 \times 16)=₹ 1600$. $$\text { S.P. of } 15 \text { articles }=₹\left(1600 \times \frac{135}{100}\right)=₹ 2160 .$$ S.P. of each article $=₹ \frac{2160}{15}=₹ 144$. If S.P. is ₹ 96, marked price = ₹ 100. If S.P. is ₹ 144, marked price $=₹\left(\frac{100}{96} \times 144\right)=₹ 150$. $$\therefore \quad \text { Marked price }=50 \% \text { above C.P. }$$
