loss of the shopkeeper by selling an eraser = 20 paise

1) in a given day total loss earned = 10 rs

loss by selling an eraser= 20 paise

As rs 1=100 paise

so rs 10= 1000 paise

So eraser sold = 1000/20=50 erasers

2) loss earned by selling of eraser= 20 paise

that day he sold 100 erasers

so loss = 20x100=2000 paise
