Question

by selling a table for $990, a trader gain 10%. find the cost price of the table​

Answer 1

Step-by-step explanation:

profit = 10% of 990 = 10/100 x 990

=99

CP (costprice)= 990-99 = 891

Answer 2

Step-by-step explanation:

Let the cost of the table be x.

selling price of the table=$990

Since, seller gains=10% on selling

so,

selling price = cost price+ 10%of cost price

$990=x + 10/100×x

$990=x + x/10

$990=11x/10

$990×10=11x

x=$990×10/11=$90×10=$900

hence ,the cost price of the table is$900
