a tv purchased for rs 14355 including tax. if the actual price of the tv is 13050 . find  the rate of interest​

Dear Student,

Please find below the solution to the asked query:

Given :  Selling price of T.V. =  Rs .14355 including tax

And

Actual cost of T.V. =  Rs .13050

So,

Tax on T.V. = 14355 - 13050 = 1305

Let rate of tax  = r  , So

r % of 13050 =  1305

$$\begin{gathered} \frac{r \times 13050}{100} = 1305 \\ \Rightarrow r = 1305 \times \frac{100}{ 13050} \\ \Rightarrow r =\frac{100}{10} \\ \mathbf{\Rightarrow }\mathit{r}\mathbf{ }\mathbf{=}\mathbf{10}\mathbf{ }\mathbf{\%}\mathbf{ }\mathbf{ }\mathbf{ }\mathbf{ }\mathbf{ }\mathbf{ }\mathbf{ }\mathbf{ }\mathbf{ }\mathbf{ }\mathbf{ }\mathbf{ }\mathbf{ }\mathbf{ }\mathbf{ }\mathbf{ }\mathbf{ }\mathbf{ }\mathbf{ }\mathbf{ }\mathbf{ }\mathbf{ }\mathbf{ }\mathbf{ }\mathbf{ }\mathbf{ }\mathbf{ }\mathbf{ }\mathbf{ }\mathbf{ }\mathbf{ }\mathbf{ }\mathbf{ }\mathbf{ }\mathbf{ }\mathbf{ }\mathbf{ }\mathbf{ }\mathbf{ }\mathbf{ }\mathbf{(}\mathbf{ }\mathbf{Ans}\mathbf{ }\mathbf{)} \end{gathered}$$
