Question

The present price of a car is rupees 33750 every year the price decreases buy 4 % find the price of the car after 4 years

Answer 1

present Price=33750Rs.
Decrease of price Per year=4%

Now,

In First Year,
4% of 33750
=(4/100)×33750
=1350Rs.
So Cost becomes: 33750-1350=32400Rs.

in 2nd Year.

4% of 32400
=(4/100)×32400
=1296

So Price=Rs.31104

In 3rd Year.

4%of 31104
=(4/100)×31104
=1244.16 Rs.

So Price=31104-1244.16=Rs 29859.84

In 4th Year

4%of 29859.84
=(4/100)×29859.84
=1194.3936 Rs.
Price=29859.84-1194.3936
=28665.4464 Rs.

So The Price of the Car after 4 years With an Annual Decrease of 4% in its Price= Rs:28665.4464

Answer 2

P = 33750
R%=4%
T = 4 years
A = P(1-r/100)^n
= 33750(1-4/100)^4
simplify it and you will get the answers
