Cost Price $\left(\mathit{C}\mathit{P}\right)$ of one fan $=$ Total Cost Price $∕$ Number of Fans
$=$ Rs. 24,000 / 12
$=$ Rs. 2,000 per fan.
Marked Price (MP) of one fan $=\mathit{C}\mathit{P}+25\%$ of CP
$=$ Rs. $2,000+0.25\times$ Rs. 2,000
$=$ Rs. 2,500 per fan.
Discounted Price (Selling Price) of one fan $=$ MP $-10\%$ of MP
$=$ Rs. $2,500-0.10\times$ Rs. 2,500
$=$ Rs. 2,250 per fan.
Total Selling Price for 12 fans $=$ Selling Price per fan $\times$ Number of Fans
$=$ Rs. $2,250\times 12$
$=$ Rs. 27,000 .
Total Profit $=$ Total Selling Price - Total Cost Price
$=$ Rs. 27,000 - Rs. 24,000
$=$ Rs. 3,000 .
