A wholesaler sells a watch to a retailer at a profit of 25% and the retailer sells it to a customer at a loss of 12%. If the customer pays Rs 1045, what had it cost the wholesaler?

For the wholesaler,

Let the cost price = Rs. $$100x$$

With profit of 25%, Selling price = $$\frac{125}{100} \times 100x = Rs. 125x$$

For the retailer,

Cost price = Rs. $$125x$$

With a loss of 12%, Selling price = $$\frac{88}{100} \times 125x = Rs. 110x$$

For the customer,

Cost price = $$110x = 1045$$

=> $$x = \frac{1045}{110} = \frac{95}{10} = 9.5$$

$$\therefore$$ Cost price for retailer = $$100 \times 9.5 = Rs. 950$$

=> Ans - (A)
