Rajan bought a watch for Z 1870 including VAT at 10%. Find the original price of the watch.


VAT = 10%


Selling Price = Rs.1870


Let × be the base price.


Vat Amount = 10% of x


= x/10


Base Price + VAT = Selling Price


× + x/10 = 1870


11x/10 = 1870


× = (1870 × 10) / 11


= Rs.1700


So, Cost Price of watch is Rs.1700
