1) [5 marks] Consider the following Integer Linear Programming (ILP) model Minimize Z=4X17X2 Subject to X1+5X210X1X21X1,X20X1,X2areinteger Consider using the Branch and Bound (B \& B) technique to solve the ILP model. With the help of Tora/Excel software, draw the B&B tree. Always give priority for X1 in branching over X2. Clearly label the constraint on each branch. Finally, find the optimum solution
