The price of an electronic machine decreased by 5%, 10% and 15% during the first three years. What will be the price of the machine after three years if the value at the beginning was ₹ 8,000?
Show answer & explanation
Correct answer: B
Explanation
The correct answer is option 2 i.e. ₹ 5,814.
Initial price = ₹ 8,000
Price of the machine after three years = 8000 × (100 - 5)% × (100 - 10)% × (100 - 15)%
⇒ 8000 × (95)% × (90)% × (85)%
⇒ 5,814
