3. A fruit seller has lemons, apples and mangoes at his stall. The price of an apple is the mean selling price of a lemon and a mango. A customer paid a sum of RM15.50 for 10 lemons, 10 apples and 5 mangoes. A second customer paid RM38.00 for 30 lemons, 20 apples and 10 mangoes. By taking the price of lemon, apple and mango as x, y and z respectively, build a system of linear equations in the form of matrices and solve the problem using Gauss Jordan elimination method to determine the selling prices of a lemon, apple and mango.
