Question

a watch was sold at a profit of 6% yeilds rupees 870 more then when it is sold at a loss of 6% find the cost price of the watch​

Answer 1

Answer:

Step-by-step explanation:

Answer:

Let the cp = 100

SP at profit=100+6/100*100= 106

SP at loss= 100-6/100*100=94

Difference between  both SPs =106-94=12

If SP = ₹12 and cp =₹100 therefor if SP = 870 then cp = how much

Cross multiplication 100*870/12

And we got the answer 7250 RS
