100% value will be =

$\frac{82}{9} \times 100\% = 911.11$

Answer 2

Answer:

911.11

Step-by-step explanation:

Here,

selling price (SP) = 820

loss (L) = 10%

cost price (CP) = ?

Let the cost price be 'x'

Then,

loss amount = L% of CP = 10% of x = 0.1x

Now,

loss = CP - SP

or. 0.1x = x - 820

or, 820  = x - 0.1x

or, 820 = 0.9x

Dividing both sides by 0.9, we get

x = 911.11
