Question

the value of washing machine depreciates 15 . every year its present value is ₹4335 what was its price 2 years ago

Answer 1

Answer:

Washing machine cost 2 year before was 6100

Step-by-step explanation:

if its percentage then

X - 15 % of X = 4335

X - 15 * X/100 = 4335

X/1 - 15X/100 = 4335

100X - 15X = 4335 *100

85X = 433500

X = 433500/85

X = 5100

Now above steps needs to be repeated again for finding the value of machine 2 years before

X = 510000/85 = 6000

So machines cost 2 year before was 6100
