Question

an article is sold for RS 420 at a loss of 10 percent, what would have been the gain or loss percent if the same article had been sold for RS 500 ?



​

Answer 1

Answer:

Let CP =x=x, so S.P =1.2x

When CP is Rs. 100 less,

CP=x−100

SP=1.2x−100

Now,

1.2x−100=1.24×(x−100)

On solving , we get

x=600

CP=Rs.600
