Answer 2

Answer:-

The cost of the bicycle when it will be 3 years old is Rs. 1280

Explanation:-

Given :

Cost of bicycle when new = Rs. 2500

At the end of each year, the worth of the bicycle is 4/5 of Rs. 2500

To find :

The worth of the bicycle when it will be 3 years old.

Solution :

First we will find the worth of bicycle after 1 year :-

$= rs. \: (\dfrac{4}{5} \times 2500)$

$= rs. \: 2000$

Therefore, Cost of bicycle after 1 year = Rs. 2000

Now, Cost of bicycle after 2 years:-

$= rs. \: ( \frac{4}{5} \times 2000)$

$= rs. \: 1600$

Therefore, Cost of bicycle after 2 years is Rs. 1600.

Now, The cost of bicycle after 3 years:-

$= rs. \: ( \frac{4}{5} \times 1600)$

$= rs. \: 1280$

Hence, The worth of the bicycle after 3 years will be Rs. 1280.
