Radhika bought a car for Rs 2,50,000. Next year its price decreased by 10% and further next year it decreased by 12%. In the two years overall decrease per
cent in the price of the car is
(a) 3.2%
(b) 22%
(c) 20.8%
(d) 8%
(c) 20.8%
Explanation: Radhika bought a car for Rs. 250000.
Cost price = Rs.250000
Its price decreased next year for 10%.
Thus, new price = 250000 – (10/100) × 250000
= 250000 – 25000 = 225000
Again, the price of car decreased by 12% next year. So the price will be:
=225000 – 225000 × (12/100)
= 225000 – 27000
= 198000
So, the overall decrease in percentage of car price = (250000-198000)/250000 × 100
= (52000/250000) × 100 = 520/25 = 20.8%
