Question

The price of a washing machine, inclusive of sales tax is Rs 13,530/-. If the sales tax is 10%, find its basic cost price.

Answer 1

The selling price of washing machine = Rs 13,530

Rate of sales tax = 10%

Let the cost price = x

`"Tax" = 10/100xxx = x/10`

Price inclusive Tax = Rs 13,530

`x/1+x/10=13530`

`(10x+x)/10 =13530`

`(11x)/10 = 13530`

`x=(13530xx10)/11`

`x = "Rs". 12300`
