Question

An object is sold at 10% profit at rupees 550 . What will be the profit percentage if the same object is sold at rupees 650

Answer 1

selling price of object = 550 Rs.

profit = 10%

so, cost price of the object = selling price - profit

⇒C.P = 550 - 10% of C.P

⇒C.P + 0.1 C.P = 550

⇒C.P = 500 Rs.

now same object is sold at 650 Rs.

so, percentage profit = (selling price - cost price )/cost price × 100

= (650 - 500)/500 × 100

= 150/5

= 30%

hence, profit percentage is 30%.

Answer 2

Answer:

Let CP = x

Then 680-x=x-420

-x-x=-420-680

-2x=-1100

x=Rs 550

Required S. P=160% of 550

=Rs 880
