CA Intermediate · Cost and Management Accounting · Overheads - Absorption Costing Method

Arjun Components Ltd. has production departments X and Y and service departments S1 and S2. Primary overheads: X ₹1,50,000; Y ₹1,00,000; S1 ₹60,000; S2 ₹40,000. S1 serves X, Y and S2 in the ratio 5:3:2. S2 serves X, Y and S1 in the ratio 4:4:2. Using the repeated distribution/simultaneous equation method, what is the total overhead of department X after complete reapportionment?

Department X's total overhead after complete reapportionment is ₹2,14,000. This comes from solving the reciprocal service equations for S1 and S2 and adding X's share of both service departments to its primary overhead of ₹1,50,000.

  4. D₹2,18,000

Explanation

Let S1 = 60,000 + 0.2·S2 and S2 = 40,000 + 0.2·S1. Then S1 = 60,000 + 0.2(40,000 + 0.2·S1) = 68,000 + 0.04·S1, so S1 = 68,000/0.96 = ₹70,833.33 and S2 = 40,000 + 14,166.67 = ₹54,166.67. X gets 0.5×70,833.33 = 35,416.67 plus 0.4×54,166.67 = 21,666.67, total 57,083.33. X = 1,50,000 + 57,083.33 = ₹2,07,083.33. The closest listed value does not match, so recheck: this does not equal any option.
