Solution -
Let,
CP of 1 gram = 1
CP of 1000 gram = 1000
MP of 1 gram = 1 × (120/100)
MP of 1 gram = 1.2
Now,
A trader use a weighing balance that shows 1250 g for a kilogram.
He charges to a customer = 1250 × 1.2
He charges to a customer= 1500 for ( Rs. 1000)
Thus,
Profit = SP - CP
= 1500 - 1000
= 500
Profit % = (500/1000) × 100
= 50%
Hence,
The correct answer is oprion (c) 50%.
