Answer 2

Percentage

Cost of scooter in 2015 $=60000 \ rupees$

Percentage of value  by which it falls every day $= 20\%$

Time period $= 2 \ years$

As per information given in question,

We can see it as ,

$rate$ $=20\%$

$n= 2 \ years$

$P=60,000\\A= ?$

$A=P(1-\frac{r}{100})^n$

$\implies A=60000(1-\frac{20}{100})^2\\\\\implies A=60000(\frac{4}{5})^2\\\\\implies A= 60000\times\frac{16}{25} \\\\\implies A=38,400$

Hence, after 2 years the price will of the scooter will be Rs.38,400.
