i need help in all these questions to solve. please help in solving these questions with working notes..

During your project analysis, you understand that there is a cost-variance in the project. Further analysis shows that it is a one-time variance caused by an unexpected rework. You do not expect such situation in future. You would like to get the Estimate at completion for your project, so you perform earned value analysis and get the following data: EV=2,000,000; PV=1,500,000;AC=2,500,000;BAC=4,000,000. What is EAC?(5 marks) Question 2 When you collect the earned value data for your project, you get the following data: PV=$1,500,000, EV=$1,200,000,AC=$1,000,000. You expect the factors for cost variance to continue in the same way in future. The value of the remaining work is $1,000,000. What should be the new EAC for the project? (5 marks) Question 3 The project is budgeted at $1,000,000. The following earned value figures have been derived. PV=$500,000;EV=$450,000;AC=$550,000. The cost variances in the project are caused by one-time factors which are no longer effective. What will be the estimate at completion for the project? (5 marks) Question 4 You are managing a telecommunications project. The project is expected to be completed in 10 months at a cost of $12000 per month. After 2 months, you realize that the project is 30% completed at a cost of $60,000. Calculate the Earned Value (EV) and the Cost Variance (CV)
