Question

by selling an article sonu makes a profit of 20%. if the cp decreased by 10% and sp also increased by 10%,calculate her profit percentage​

Answer 1

Answer:

37.8 %

Step-by-step explanation:

Let CP = 100

$SP =\frac{100+profit}{100}*CP\\\\=\frac{120}{100}*100$

SP = 120

New CP:

CP decreased by 10%

 $Decreased \ amount=\frac{10}{100}*CP\\\\=\frac{10}{100}*100$

 = 10

New CP = 100- 10 = 90

New SP:

SP increased by 10%

Increase amount = $\frac{10}{100}*old \ SP$

                            $= \frac{10}{100}*120\\\\= 12$

New SP = 120 + 12 = 132

Profit = new SP - new CP

         = 132 - 90 = 42

Profit percentage = $\frac{Profit}{CP}*100$

                             $= \frac{42}{90}*100$

                             = 46.67%
