Question

The price of book is first increased by 20% then decreased by 10%. If the price of the book is now rs 216 what was the original price of the book

Answer 1

Answer:

Step-by-step explanation:

The original price is P. If it increased by 20%, that means 20% of the original price was added. Similarly, if it decreased by 10%, that means that 10% of the original price was added. This is how you get the current price

Therefore,

P+ (P×0.20)-(P×0.10)= 216

combine the terms,

1.10P=216

P=$196.36
