Question

Price of book is increased 20% that is ₹145.60 , find its original price

Answer 1

Answer:

Step-by-step explanation:

Hello,

let the original price of the book= x

Now,

 rate of increase=20%;

increase in price=20%of x= 20/100×x=0.2x

Then,

incresed price=x+0.2x=1.2x

but increased priced=145.60,

so,

1.2x=145.60;

x=145.60/1.2=121.3

x=121.3

therefore original price of the book is 121.3 Rs.
