- A9%
- B11%
- C10%
- D13%
Solution & Step-by-step Explanation
Let the selling price (SP) of 1 notebook be ₹1.
SP of 80 notebooks=₹80
Loss=SP of 10 notebooks=₹10
The relationship between Cost Price (CP), SP, and Loss is:
CP=SP+Loss
CP of 80 notebooks=80+10=₹90
Now, calculate the loss percentage:
Loss %=(
CP
Loss
)×100
Loss %=
