Question:
After a 20% hike, the cost of Chinese Vase is Rs 2000. What was the original price of the object?
Solution:
Let the original price of the object be $x$.
According to the question, we have:
$20 \%$ of $x+x=2000$
$\Rightarrow \frac{20 x}{100}+x=2000$
$\Rightarrow \frac{120}{100} x=2000$
$\Rightarrow x=\frac{200000}{120}$
$\Rightarrow x=1666.67$
Thus, the original price of the object was Rs $1,666.67$.
