a man sold a watch for 600 rs at a loss . had he sold it for 750 rs , his gain would have been double the former loss . the cost price of the watch is ?​

Answer»

Step-by-step EXPLANATION:

LET the cost PRICE of watch is Rs. x

Then loss = Rs. x−600

If watch sold Rs. 750, then PROFIT = Rs. 750−x

Given gain has been double the loss

Then 750−x=2(x−600)

⇒750−x=2x−1200

⇒x=650

Therefore, the cost price of the watch is Rs. 650.
