If he made 25 percent profit, the selling price (1200 naira) is 125 percent.

If 125% is equal to 1200 naira

100 percent (the original) will be 100 × 1200 divided by 125

Which is 120000 ÷ 125

Therefore, the cost price is 960 naira

Answer:

the cost price is 960/-

Step-by-step explanation:

Selling Price = 1200

Profit = 25%

Finding the cost price:

Let the cost price be x

Then,

x = 1200-0.25x

=> x+0.25x = 1200

=> 1.25x = 1200

Dividing both sides by 1.25

=> x = 960

So the cost price is 960/-
