A furniture dealer sold two chairs for $300 each. He made a profit of 25 percent on one of the chairs and a loss of 25 percent on theother. What was his overall loss or profit percentage on selling both the chairs?
Given:
To Find: Overall profit or loss% on selling both chairs?
Approach:
2. The cost price of the chairs can be found out using the information given about the selling price and the profit% or loss%
3. Cost Price and profit on chair1
As we know the selling price and the profit%, we can calculate the Cost price of chair1. Once we know the cost price, we can calculate profit made on the chair using (2).
4. Cost Price and loss on chair2
Selling Price = Cost Price  Loss……..(4)
As we know the selling price and the loss%, we can calculate the Cost price of chair2. Once we know the cost price, we can calculate loss made on the chair using (4).
5. Now, as we know the cost price of the chairs and profit or loss made on the chair, we can calculate the profit or loss% using (1)
Working out:
a. Selling price of the chair = $300
b. Profit% on the chair = 25%
c. So, we can write
2. Cost Price and loss on chair2
a. Selling price of the chair = $300
b. Loss% on the chair = 25%
c. So, we can write
3. As the loss made on chair2 is greater than the profit made on chair2, total
loss made = 100 – 60 = $40
Hence, the shopkeeper made a loss of around 6% on the total transaction

A light bulb manufacturer ships 10 boxes consisting of 100 light bulbs each to a retailer. The manufacturer bills the retailer at a rate of $10 per bulb with a condition that the defective light bulbs may be returned to the manufacturer for full refund. The probability of a light bulb in a box being defective is 20 percent. If the manufacturer makes a profit of 100 percent on each nondefective light bulb and he has to bear a return shipment cost of $2.5 per defective light bulb, which he treats as lost revenue, what is the profit percentage of the manufacture on the whole transaction?
Given:
To Find: Total Profit % of the manufacturer?
Approach:
a. Hence the total net revenue of the manufacturer can be calculated as
Total Net revenue=(Total revenue from nondefective light bulbs) (Total lost revenue from defective light bulbs)
b. As we know the selling price of each nondefective light bulb and the number of nondefective light bulbs, we can calculate the total
revenue of the manufacturer from the nondefective light bulbs as
Total Revenue from non − defective light bulbs
c. Also, the manufacturer has to recognise the shipment charges of the defective bulbs as lost revenue, it can be calculated as
4. Total Cost Calculation
Selling Price = Cost Price + Profit ..............(1)
Also, we know that,
Working out:
1. Calculating number of Defective and Nondefective light bulbs
a. Total number of bulbs shipped = 1000
b. Total defective light bulbs = 0.2 * 1000 = 200
c. So, total nondefective light bulb = 1000 – 200 = 800
2. Total Net Revenue Calculation
a. Selling price of each nondefective light bulb = $10
b. Total revenue on the nondefective light bulbs = 800 * 10 = $8000
c. Lost revenue for each defective light bulb = $2.5
d. So, lost revenue for total defective bulbs = 2.5 * 200 = $500
e. Hence total net revenue = $(8000 – 500) = $7500
3. Total Cost Calculation
a. Selling price of each nondefective light bulb = $10
b. Profit % on each nondefective light bulb = 100%
c. Cost price of each light bulb = $5
d. Total cost in producing all the light bulbs = 1000* 5 = $5000
4. Profit made = $(7500 – 5000) = $2500
5. Profit % = %
Hence the manufacturer made a profit of 50% on the whole transaction.
