Question

the present price of a car is rupees 33750. Every year the price decreases by 4% . find the price of the car after 4 years ​

Answer 1

Step-by-step explanation:

Step 1:

because the price of car decrease every year at the rate of 4%

so wo can used the formula of compound interest but with different logic.

by the way the formula of compound interest is

CI= P(1+R/100)^n

here the price is decreased every year so used negative sign

CI=P(1-R/100)^n

Step 2:

=33750(1-4/100)^4

=33750(24/25)^4

= 33750 * 24/25 * 24/25 * 24/25 * 24/25

=28665.45rs.
