Some articles were bought at 6 articles for\( Rs. 5\) and sold at 5 articles for \(Rs. 6.\) Gain percent is:
Answer: D
Suppose, number of articles bought \(= L.C.M.\) of \(6\) and \(5 = 30.\)
Cost Price of \(= Rs. (\frac{5}{6} \times 30) = Rs. 25.\)
Selling Price of \(30\) articales \(= Rs. (\frac{6}{5} \times 30) = Rs. 36.\)
\(\therefore\) Gain % \(= (\frac{11}{25} \times 100)\) % \(= 44\) %.
