Question

If the manufacturer gains 10%, the wholesale dealer 15% and the retailer 25% then what is the cost of production of the electric heater whose retail price is ₹1265?

Answer 1

Let the cost of Production = Rs. P
Then, as per question,

\begin{aligned}
=> \left( \frac{125}{100} *\frac{115}{100}*\frac{110}{100} * P \right) = 1265\\
=> \frac{253}{160}P = 1265 \\
=> P = 800
\end{aligned}
