Question

hi plz tell me this subject maths​

Answer 1

Let the value be 100x last year. = 100x-100x*20/100 = 80x. Also this year's price=160000. So 80x= 160000.

Answer 2

Let the value of machine last year be X.

so after one year the depreciation in value is 20% of X

i.e., X (20/100) = 0.2X

The value of the manchine after depreciation = X - 0.2X

= 0.8X

But it is given that the current value of the machine = 160000.

=> 0.8 X = 160000

=> X = (160000/0.8)

X = 200000.

Hope this helps you ✌️✌️☘️☘️.
