A shopkeeper advertises for selling cloth at 4% loss. However, by using a false meter scale he actually gains 20% . What is the actual length of the scale___________?
- 65 cm
- 55 cm
- 40 cm
- 90 cm
- 80 cm
Explanation
Let the percentage deduction in weight be y%
y−4100−y×100=20⇒y−4100−y=15⇒5y−20=100−y⇒6y=120⇒y=20
Hence, for a meter, length used = (100 - 20)% of 1 m
= 80% of 100 cm = 80 cm
