Question

By selling a product for Rs. 720, a loss of 10% is obtained. At what price the product must be sold to get 20% gain?​

Answer 1

Answer:

If SP= 720

loss = 10%

so

$cp = ( \frac{100}{100 - l} ) \times sp \\ cp = (\frac{100}{100 - 10} ) \times 720 \\ cp = \frac{100}{90} \times 720 = 800$

cp = 800

profit = 20%

so

$sp = ( \frac{100 + p}{100} ) \times cp \\ sp = ( \frac{100 + 20}{100} ) \times 800 \\ sp = \frac{120}{100} \times 800 = 960$

It should be sold for 960 to get 20% profit
