Answer 1

hey dear,

ur answer goes like this:-

--------------->>>>>>>>>>>>>>>---------------

let the cost of car two years ago was Rs 'x'.

now,

A/Q,

its cost depriciates at the rate of 20% every year.

So,price after two years from two years ago.

A = p (1 - r/100)²

252480 = p (1 - 20/100)²

=>252480 = p (4/5)²

=>p = 252480 × 25/16

=>p = 394500 Ans.

Thus,purchase price = Rs 394500.

Again,

current price = Rs.252480

So,price after two years from now

= 254280(1 -20/100)¹

= 254280(4/5)

=Rs.201984 Ans.

------------------>>>>>>>>>>>>>-------------


Learn the formula please:-

in case of depreciation,price after n years at the rate of r℅ =

p (1 - r/100) ^n
