Question

The profit earned when the book is sold for rs800 is thrice the profit earned when the same book is sold for rs500.what should be the selling price if seller wants to earn 40% profit?

Answer 1

Answer:

490

Step-by-step explanation:

he got thrice profit when it sold to 800 , before 500

then the gap 300 is twice the profit earned on 500

so one time profit = 150

then 500- 150 = 350 is the cost price

100% cost price = 350

profit 40 % required = 140% c.p= 350*140/100 = 490
