Question:

Dinesh purchases a washing machine for ₹24000. The value of machine is depreciating at the rate of 5% p.a. Calculate its value after 3 years

Options:

19785

22786

20577

21577

Correct Answer:

20577

Explanation:

The correct answer is option (3) : 20577

Given $P= ₹24000$

$i=\frac{5}{100}=0.05$

$n= 3\, years $

So, $ S= 24000 (1-0.05)^3$

$= 24000 (0.95)^3$

$= 24000×0.857375$

$= 20577$
