  • Profit and Loss

Profit and Loss:

1. Profit = Selling price (S.P.) – Cost Price (C.P)

2. Loss = Cost Price (C.P.) – Selling Price  (S.P.) 

Where;

Selling price: Selling price is the price at which a good or service is sold. 

Cost Price: Cost price is the price at which a good is bought. 

When S.P. > C.P., a profit is made 

When C.P. > S.P., a loss is made 

3. Percentage profit = \( \frac{Profit}{Cost \: Price}\scriptsize \: \times \: 100 \% \)

4. Percentage loss = \( \frac{Loss}{Cost \: Price}\scriptsize \: \times \: 100 \% \)

5. Profit = Percentage \(\scriptsize \: \times \: \) Cost price 

Example 1.5.1:

A farmer buys an animal for ₦40 000 and sells it for ₦33 000. What is the percentage loss? 

Solution 

C.P. = ₦40 000 

S.P. = ₦33 000 

Loss = ₦40 000 – ₦33 000

= ₦7000

Percentage loss = \( \frac{Loss}{Cost \: Price}\scriptsize \: \times \: 100 \% \)

= \( \frac{7,000}{40,000}\scriptsize \: \times \: 100 \% \)

= \( \frac{7,\not{0}\not{0}\not{0}}{40,\not{0}\not{0}\not{0}}\scriptsize \: \times \: 100 \% \)

= \( \frac{7}{40}\scriptsize \: \times \: 100 \% \)

= \( \frac{700}{40}\% \)

= \( \frac{70\not{0}}{4\not{0}}\% \)

= \( \frac{70}{4}\scriptsize \% \\ = \frac{35}{2}\scriptsize \% \\ = \scriptsize 17 \frac{1}{2} \% \\ = \scriptsize 17.5 \% \)

Example 1.5.2:

Find (i) the profit or loss and (ii) the selling price, for these cost prices. 

(a) ₦400, profit 20% 
(b) ₦375, loss 8%
