The cost price of an article is Rs. 1,200 and selling price is $\frac{5}{4}$ times of its cost price.

Find:
(i) The selling price of the article
(ii) Profit or loss as a percent.

(i) Cost price (CP) = Rs. 1200
$\therefore \text{SP}=\frac{5}{4}\text{of CP}$
$=\frac{5}{4}\times 1200$
$\text{Rs}.1500$

(ii) Gain = SP - CP
= 1500 - 1200
= Rs. 300
$\therefore \text{Gain}\%=\frac{\text{Gain}\times 100}{\text{CP}}$
$=\frac{300\times 100}{1200}$
$=25\%$
