Question

9. A shopkeeper buys 40 erasers for 240 and sells them at the rate of 30 erasers for 165 find his profit or loss per cent.​

Answer 1

Answer:

C.P for a eraser = 240/40

C.P for a eraser = ₹6

S.P for a eraser = 165/30

S.P for a eraser = ₹5.5

Loss = S.P - C.P

Loss = ₹6 - ₹5.5

Loss = ₹0.5

Loss% = loss/C.P × 100

Loss% = 0.5/6 × 100

Loss% = 8.3%
