Question
A manufacturing company acquired a specialized machine
for ₹10,00,000 with an original estimated useful life of 10 years and zero residual value. After exactly 3 years of using the Straight-Line Method (SLM) of depreciation, the technical team determines that due to superior maintenance, the machine's total useful life should be 12 years from the date of acquisition. As per accounting standards, how should this be handled?Solution
Revisions in useful life, residual value, or the expected pattern of consumption of future economic benefits are classified as Changes in Accounting Estimates , not policies or errors. Under Ind AS 8 , changes in estimates are always handled prospectively . This means the company does not fix the past but only adjust the current and future periods. The future depreciation calculation will be done as follows:
- Cost: ₹10,00,000
- Depreciation for 3 years already applied as per SLM: (10,00,000÷10)×3=3,00,000
- Carrying Amount at end of Yr 3: 10,00,000−3,00,000=7,00,000
- New Total Life: 12 years
- Remaining Life 12 (New Total) − 3 (Years Lapsed) = 𝟗 Years
- Future Impact: For Year 4 onwards, the annual depreciation will be 7,00,000÷9 = 77,778 (instead of 1 lakh earlier)
- What will come in the place of question mark (?) in the given expression?
389 + 641 - ? = 180 X 2 - Simplify:

√529 * 5 – 15% of 220 + ? = 120% of 160
[(120)2 ÷24 ×25] ÷ 250 =?
17.6% of 250 + √? = 70% of 90
{(522 – 482 ) ÷ (27 + 73)} × 35 = ?% of 17
√1936 + √3025 = ? % of 220
√ 225 x 24 - √ 144 x 18 = ?
What will come in the place of question mark (?) in the given expression?
(40/25) X 80 - ? = 45% of 300 - 55(22% of 1500 + 15% of 2200) = ? x 11
