A garage owner sell two cars for N300 000 thereby making profit of 20% on the cost price of the second. Find the loss or gain percent on the total cost price. I believe the total selling price = 300 000. My problem is how to get selling price of each of the car.

There isn't enough information to begin answering this.

Without further information, there would be numerous possibilities, such as each car having a cost price of N160000, the first being sold for N208000 (a profit of 30%), and the second being sold for N192000 (a profit of 20%).
