A shopkeeper wishes to give 5%commission on the marked price of an article but also wants to earn a profit of 10%. If his cost price is Rs. 95, then the marked price is
Cost price(CP) = 95

Profit = 10 %
$$ \frac{SP -CP}{CP} \times 100 = 10 % $$
Substituting,
$$ \frac{MP \times \frac{95}{100}}{95} = \frac{11}{10} $$
Solving, MP = 110
