Step-by-step explanation:
and i have no idea why the answer was 720000 in your book, im sorry mate
Given:
Increase in the price of book=12%
Increased price= ₹145.60
To find:
The original price
Solution:
The original price of the book is Rs. 130.
We can find the price by following the given steps-
We know that the increase of 12% is on the original price of the book.
Let us assume that the original price of the book is X.
So, an increase on it would be equal to 12% of X.
Increase in the original price=12X/100
After the increase, the price becomes= X+12% of X
=X+12X/100
Increased price=112X/100
112X/100=145.60
112X/100=14560/100
112X=14560
X=14560/112
X=130
Original price, X= Rs. 130
Therefore, the original price of the book is Rs. 130.
