Question

By selling a book for Rs 50, a shopkeeper suffers a loss of 10%. The cost price of the book is Rs 60.

Answer 1

Given: The selling price = Rs 50, loss percent = 10%

To find: Is cost price Rs 60 or not?

Solution:

• Now we have given the selling price as Rs 50 and loss percent as 10%.

• We have the formula for loss percent as:

                loss % = loss/CP  x  100

                loss % = ((CP - SP)/CP)  x  100

• Now putting the values we get:

                10 = CP - 50/CP x 100

                10 CP = 100 CP - 5000

                90 CP = 5000

                CP = 5000/90

                CP = 500/9 = 55.55

Answer:

         So its false, the cost price id Rs 55.55

Answer 2

Answer:

Solution:

Now we have given the selling price as Rs 50 and loss percent as 10%.

We have the formula for loss percent as:

               loss % = loss/CP  x  100

               loss % = ((CP - SP)/CP)  x  100

Now putting the values we get:

               10 = CP - 50/CP x 100

               10 CP = 100 CP - 5000

               90 CP = 5000

               CP = 5000/90

               CP = 500/9 = 55.55

Answer:

        So its false, the cost price id Rs 55.55
