Question
A TV was bought at a price of ₹ 21,000. After one year the value of the TV was depreciated by 5% (Depreciation means reduction of value due to use and age of
the item). Find the value of the TV after one year.
Sum
Solution 1
Principal = ₹ 21,000
Reduction = 5% of ₹ 21000 per year
= ₹ `(21000 xx 5 xx 1)/100`
= ₹ 1050
Value at the end of 1 year = ₹ 21000 - ₹ 1050 = ₹ 19,950.
