Question

Tanvi bought a watch for rs 1980 including VAT at 10/ find the original price of watch

Answer 1

price of watch (100%) + VAT (10%) = 110%
110% = 1980
100% =( 1980/110) × 100 = 1800

ie actual cost of watch is 1800

Answer 2

Given that,

Selling price of watch is Rs 1980.

VAT on watch is 10%

To find,

The original price of watch.

Solution,

Let original price of the watch is x.

Amount of VAT= $10\%\ \text{of}\ x=\dfrac{x}{10}$

According to given condition,

$x+\dfrac{x}{10}=1980\\\\\dfrac{11x}{10}=1980\\\\x=\dfrac{1980\times 10}{11}\\\\x=1800$

Hence, the original price of the watch is Rs 1800.
