The cost of making a painting increased by 18% as a result of the increase in the cost of paints. A painter revised the selling price of painting so as to maintain the same profit. percentage as before

Answer 2

Let,s consider the cost price = Rs 100

And also consider Selling price = Rs X

∴ profit  will be = ( SP -CP)

                            = ( X-100)

profit % will be = (X-100)%

According the question, the new cost price will be =18% of 100 = 118

∴ profit will be  118% of ( X-100)

According the sum,[118/100 ( X-100) -( X-100)] = 9

                              ⇒( X-100) ( $\frac{118}{100}$ -1) =9

                              ⇒( $\frac{118-100}{100}$) ( x-100)=9

                             ⇒$\frac{18}{100}$ ( X-100) =9

                             ⇒$\frac{9}{50}$ ×9 = (X-100)

                             ⇒$\frac{1}{50}$ =(X-100)

                            ⇒ ( X-100) = 50

                             ⇒x= 100 +50

                            ⇒X= 150

Hence earlier profit per painting was = ( SP- CP0 = ( 150 -100) = Rs 50

Ans :- The earlier profit per painting was Rs 50.
