Question

a man purchased two watches at rupees 1025 he sold the watches at the same price in one watch there was a profit of 20% and in the other watch there was a loss of 15% find the cost price of each watch​

Answer 1

Answer:

Let the price of the 2 watches be x and y.

Thus x+y=560

Now let x be sold at 15% profit and y be sold at 10% loss.

Thus 115x+90y=56000

Or 115x+90(560-x)=56000

Or 115x-90x+50400=56000

Or 25x=5600

Or x=224

Thus y=336
