agr apki baat ko mana jae tou phr april me jo office equipment aur machinery purchase ki hai uski b hum ko complete year k bajae sirf 9 months ka Dep: exp account for krna parega.. marks ko samne rkhte hi assumption use kr k calculations ko simplfy kia hai.

Assumption ye tha k jis year me purchase kro us me full depreciation expense account for karo aur jis me dispose off kro us me account for nh kro. par last me jo disposal hua h usne pora year economic benefit die hain so usko depreciate kia mene..

this is my suggestion.. what you say.. me solve this question with both method..one i post and second you point out..

and thanks for checking.
