Solution

\[\text { Given, } \]

\[\text { MP of the fan = Rs } . 1250\]

\[\text { Discount = 10 % } \]

\[\text { So, Discount = 10 % of } 1250\]

\[ = 0 . 10 \times 1250\]

\[ = Rs . 125\]

\[\text { Since SP = MP - Discount }, \]

\[\text { SP = Rs } . \left( 1250 - 125 \right)\]

\[ = Rs . 1125\]

\[\text { Now }, \]

\[\text { SP of the fan = Rs  }. 1125\]

\[\text { Profit = 25 % } \]

\[CP = \left[ \frac{100}{\left( 100 + \text { Profit % }\right)} \times SP \right]\]

\[ = \left[ \frac{100}{125} \right]1125\]

\[ = Rs . 900\]

\[\text { Thus, the cost price of the fan is Rs } . 900 .\]
