Question:
Vikram bought a watch for Rs 825. If this amount includes 10% VAT on the list price, what was the list price of the watch?
Solution:
Let the list price of the watch be Rs. $x$.
Then,
$x+\frac{10}{100} x=825$
$x+0.1 x=825$
$1.1 x=825$
$x=\frac{825}{1.1}$
$=$ Rs. 750
Thus, the list price of the watch is Rs. 750 .
