if a person buy a book rs 36 the available on discount 40 % find the original price
0.6x = 36
x = 60
60*40/100=24and 60-24=36,so the answer is 60
To find the original price of the book before the discount, we need to use the discount percentage and the discounted price.
Let's assume the original price of the book is 'P'. According to the given information, the book is available at a 40% discount. Therefore, after the discount, the person pays 60% of the original price.
In mathematical terms, we can write:
Discounted price = Original price - (Discount percentage * Original price)
or
36 = P - (40% * P)
Now, let's solve the equation to find the original price.
Step 1: Convert the discount percentage into decimal form. 40% = 0.40.
Step 2: Substitute the values into the equation.
36 = P - (0.40 * P)
Step 3: Simplify the equation.
36 = 0.60 * P
Step 4: Divide both sides of the equation by 0.60.
P = 36 / 0.60
Step 5: Calculate the original price.
P = 60
Therefore, the original price of the book is Rs. 60.
