Question

a man sold a watch at a prfit of 10%. had he sold it for rs 150 more the profit qould have been 15%.find the cost price of the watch​

Answer 1

Answer:

Rs 2700

Step-by-step explanation:

Profit percentage = 10%

If he had sold it for Rs 150 more, then the profit would be 15%. Correct ?

So, 10 ( Actual Profit ) + 150 ( Cost ) = 15 ( Expected Profit )

      150 = 15 - 10

      150 = 5%

If, 5% = 150

   100% ( 5*20 ) = 3000 ( 150*20 )

So, the cost price including profit is Rs 3000

Cost price without profit = 3000 - 10% ( Actual Profit )

                                         = 3000 - 300 = Rs 2700
