Question

Find the loss percent if selling price of a book is Rs.40 and cost price Rs.45.​

Answer 1

Answer:

Loss percent = 11.11%

Step-by-step explanation:

Loss is when SP < CP

Therefore, it's a loss as SP < CP,

                  where, SP = Rs 40 and CP = Rs 45

                 

So, loss percent = {(CP - SP)/CP} * 100

                           = {(45-40)/45} * 100

                           = {5/45} * 100

                           = 1/9 * 100

                           = 100/9

                           = 11.111111111... and goes on {11.11}

So, loss percent is 11.11%....
