Question

The value of a car decreases annually by 20%. If the present value of the car is 22500,
will be its value after two years?​

Answer 1

Answer:

Present value of car (x) = 22,500

Annually decrease of the value = d =20%

Car value after two years,

= present value × (100-d)/100×(100-d)/100

= 22,500 × (100-20)/100×(100-20)/100

= (22,500×80×80)/(100×100)

= Rs. 14,400

Value of the car after 2 years = Rs. 14,400
