Question

A dealer sells a book for Rs. 24 and losess as much percent as the cost of book. Find the cost of book.​

Answer 1

Answer:

29.76

Step-by-step explanation:

selling price=24

Loss=24%

therefore,loss=24/100*24

=5.76

since it is a loss,sp<cp

cost=24+5.76

=29.76

Answer 2

Answer:

60,40

Step-by-step explanation:

Let the cost of book be x

S.P=24

loss=x-24

loss%=x-24/x * 100 = CP/x

(x-24)100=x^2

x^2-100x+2400=0

(x-60)(x-40)=0

x=60 or x=40

So,the cost of book is 60,40.
