A dishonest shopkeeper promises to sell his goods at its CP but he uses 960 gm weight instead of 1 kg. Find Profit %.
Answer & explanation
Correct answer: option 1
Gain = 1000 - 960 = 40
His new cost price = 960 (He uses 960 gm weight out of 1000 gm weight)
Gain % = \(\frac{40}{960}\) × 100
= 4\(\frac{1}{6}\)%
