The correct option is
D Rs. 3,29,200
Balance in provision for depreciation account
= accumulated depreciation on Machinery from 1.4.2014 to 31.03.2015
(3 years) + depreciation on new machinery
= (1,20,000 + 1,08,000 + 97,200) + 4,000
= RS-3,29,200.
Working notes:-
1) Accumulated depreciation on old machinery from 1.4.2014 to 31.03.2015
(WDV basis)
Depreciation for 1st year:-
= 12,00,000 x 10/100
= RS-1,20,000.
Depreciation for 2nd year:-
= (12,00,000 - 1,20,000) 10,80,000 x 10/100
= RS-1,08,000.
Depreciation for the 3rd year :-
=(10,80,000 - 1,08,000) 9,72,000 X 10/100
= RS-97,200.
2) Depreciation on new machinery :-
= RS-80,000 x 10/100 x 6/12 (October to march)
= RS-4,000.
