please help me with this i need the answer asap with explaination pls

Problem Solving. Analyze the given problem and perform the required tasks in the worksheet provided. JRD Company has two service departments and three producing departments each producing a separate product. For a number of years, the company has allocated the overhead costs of the service departments to the producing departments on the basis of annuals sales pesos which lead serious inequities. The auditor recommended that maintenance and engineering service hours be used as a better service cost allocation basis. The following date was available: Service Departments Maintenance Engineering Dept.A Producing Departments Dept. B Dept.c 400 800 Maintenance hours Engineering hours Overhead costs 400 P12,000 200 400 P90,000 800 P80,000 200 400 P50,000 P54,000 1. Using the simultaneous equations(reciprocal method), what would be the total Engineering Department cost after allocation of interservice department costs, but before allocation into the Maintenance and Production Departments? 2. Assume that the Engineering Department's total costs to be allocated is P60,000, how much of this costs is allocated to Department A, B, and C under the reciprocal method, 3. Using the reciprocal method, what would be the total Maintenance Department cost after allocation of interservice departments costs, but before allocation to the Engineering and Production Department? 4. If the Maintenance Department's total cost to be allocated is P24,000, what portion of the Maintenance Department's costs is allocated to Department A under the reciprocal method? 5. Using the direct method of cost allocation, how much maintenance cost would be allocated to the Engineering Department? 6. Using the direct method of cost allocation, how much amount of mainter=nance costs would be allocated to Department C? 7. Under the direct method of cost allocation, what amount of Enginnering Department's cost would be allocated to Department A? 8. Under the step method of cost allocation, what amount of Maintenance Departments cost is allocated to Engineering Department? 9. Under the step method of cost allocation, assuming that the cost of Maintenance Department's cost is allocated first, what amount of maintenance cost would be allocated to Department B? 10. Assuming the Maintenance Department cost is allocated first, what amount of Engineering Department cost is allocated to the Maintenance Department under the step method? 11. If the Maintenance Department cost is allocated first what amount of Engineering Department's cost would be allocated to Department C? 12. Under the step method of cost allocation, what is the total amount of Service Department's cost is allocated to Department A
