Answer:
Shopkeepers gain just by weighing is 22.22%
Step-by-step explanation:
Explanation:
Assume that the shopkeeper bought x units of goods i.e. actual weight of goods.
As the balance used to buy goods weighs 10% more, he actually bought x×110100=1.1x weight units i.e. although the shopkeeper paid for x units, he actually bought 1.1x units by weight.
Now he has 1.1x units of goods, but for selling he uses another balance, which actually measures 10% less i.e. 1−0.10=0.9 units for each unit weight of goods sold.
So while selling 1.1x becomes 1.1x0.90=1.2222... units.
Hence, shopkeepers gain just by weighing is 22.22%

The profit is calculated by subtracting the expenses from the revenue.
For Deal A:
Profit = $100,000 - $10,000
= $90,000
Deal B:
Profit = $50,000 - $20,000 = $30,000
For the percentage of revenue, we divide the revenue by the expense and multiply the quotient by 100%
Deal A: %revenue = $100,000/$10,000 x 100 = 1000%
Deal B: %revenue = $50,000/$20,000 x 100 = 250%
