Home » Aptitude » Percentage » Question

The value of a car at the beginning of a year is 10% less than the value of the same car at the beginning of the previous year. If the car is valued at Rs. 1,45,800 on 1st January, 2000, what was its value on 1st January, 1997 ?

1. Rs. 200000
2. Rs. 250000
3. Rs. 185000
4. None of these

Correct Option: A

Clearly, if the car is valued at
Rs. 90 in 2000, it was valued at
Rs. 100 in 1999.
∴ Value of the car in 1999

=	145800 × 100
	90

In this way, value of car in 1997

=	145800 × 100 × 100 × 100	= Rs. 200000
	9 × 9 × 9
