Answer 1

Given :- The price of a book is depreciated by one-fifth in a year. find the rate of depreciation. ?

Solution :-

Let us assume that , the price of a book is Rs . x .

now,

→ Original Price of book = Rs. x

→ Price depreciated in a year = (1/5) of original Price = (1/5) of x = Rs. (x/5)

therefore,

→ Rate of depreciation = (Decreased Price * 100) / Original Price = {(x/5) * 100)} / x = (x * 100) / (5 * x) = 20% . (Ans.)

Hence, Rate of depreciation is 20% .
