Answer 2

Answer:

Given:

Cost Price = Rs. 9

Profit = 10%

Expenses = 15%

To Find:

How much % should be increased for marked Price = ?

Solution:

Let SP of article be Rs.x

Expenses= 15% of x

Profit = 10% of x = 0.10 x

CP = Rs. 9

Therefore , 9 + 0.15x + 0.1x = x

x = 12

Therefore , % increase for marked price :

\begin{gathered} \implies \bold{\frac{12 - 9}{9} \times 100} \\ \\ \implies \bold{ \frac{3}{9} \times 100} \\ \\ \bold {\implies{ \frac{100}{3} \%}} \\ \\ \implies \bold \red {\underline{33.33\%}}\end{gathered}

⟹
