Construction company has four big front-end loaders located at four different workshops. The loaders must be moved to four different construction sites. The distances in kilometers are

tabulated below.

Loader A B C D Total distance

1 90 75 75 80 320

2 35 85 55 65 240

3 125 95 90 105 415

4 45 110 95 115 365

Total distance 295 365 315 365

Site

(a) How should the loaders be moved in order to minimize the total distance travelled? [6]

(b) Formulate the linear programming model for the data provided. [6]

(c) Formulate the dual model for the primal in (b). [6]

(d) Use the North-West Corner method to solve the problem. ​

step-by-step explanation:

if you want to solve percent error follow these steps.

1. subtract the accepted value from the experimental value.

2. take the absolute value of step 1.

3. divide that answer by the accepted value.

4. multiply that answer by 100 and add the % symbol to express the answer as a percentage.

if you want to solve percent of change just do this.

1. work out the difference (increase) between the two numbers you are comparing.

2. divide the increase by the original number and multiply the answer by 100. if your answer is a negative number then this is a percentage decrease.

hope this : )
