An article is marked 27% above its cost price. If x % discount is allowed on the marked price and still there is a profit of 6.68%, then what is the value of x ?

16

Let the cost price = 100

Then, the marked price = 127

Now the profit = 6.68%

Means the SP is 106.68

So the discount = 127 - 106.68 = 20.32

Discount% = \(\frac{20.32 × 100}{127}\) = 16%
