Answered by admin @



Hi,

Present value of the car ( x ) = Rs3,45,000

Annually decrease of the value = d = 20%

Car valueafter 2 years

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

= 345000× ( 100 - 20 )/100× ( 100 - 20 )/100

= ( 345000 × 80 × 80)/ ( 100 × 100 )

= Rs 2, 20,800

Value of the cat after 2 years = Rs 2,20,800

I hope this helps you.

:)
