Question

The value of a machine purchased for 200000 ruppees depreciates at the rate of 10% every year. What will be the cost of the machine after 3 years.​

Answer 1

Answer:

145800 Rs

Step-by-step explanation:

Just use the formula,

Price after 'n' years = Current Price × [1 - (rate/100)]∧n

∴ Price after 3 years = 200000 × [1 - (10/100)]∧3

⇒      "           "            = 200000 × [1 - (1/10)]∧3

⇒      "           "            = 200000 × 9/10 × 9/10 × 9/10

⇒ ∴ New Price          = 200 × 729

⇒      "           "            =  145800 Rs       ←ANSWER
