Ravi bought a mixer grinder for Rs. 6600 including a tax of 10%. What was the price of the mixer grinder before VAT was included?

$$\begin{gathered} Given, Selling price of mixer grinder = Rs.6600 \\ VAT included in the price = 10\% \\ Let us unders\tan d first for Rs.100, in general. For Rs.100, 10\% VAT will be = 10 \\ If we add the VAT to Rs.100, then the selling price becomes 100 + 10 = Rs.110 \\ Therefore, The price including tax is Rs 3300, the original price = 100/110 x 6600 = 6000 Hence, the price of mixer grinder before adding Value added tax was Rs.6000. \end{gathered}$$
