A dealer buys an article marked at Rs. 25000 with 20% and 5% off. He spends Rs. 1000 for its repair and sells it for Rs. 25000 what is his gain or loss percent ?

Solution (By Examveda Team)

Marked price of an article = Rs. 25000
After discount, cost price
$$ = {\text{Rs}}{\text{. 25000}} \times \frac{{80}}{{100}} \times \frac{{95}}{{100}}$$
= Rs. 19000
After repair, cost price
= Rs. 19000 + 1000
= Rs. 20000
Selling price of an article = Rs. 25000
$$\eqalign{ & {\text{Gain}}\% \Rightarrow \frac{{25000 - 20000}}{{20000}} \times 100 \cr & {\text{Gain}}\% \Rightarrow \frac{1}{4} \times 100 \cr & {\text{Gain}}\% \Rightarrow 25\% \cr} $$
