Quantitative Aptitiude (CLAT) Percentage

The value of a machine depreciates every year at the rate of 10% on its value at the beginning of that year. If the present value of the machine is Rs. 729, its worth three years ago was:

Rs. 947.70

Rs. 1,000

Rs. 750.87

Rs. 800

Explanation:

? P (1 - 10/100)³ = 729
∴ P = Rs.(729 x 10 x 10 x 10)/(9 x 9 x 9) = Rs. 1000
Hence, option 2 is the correct answer.
