Question

The price of a book is increased by 12%
If its increased price is 145.608 find its
original pornice.​

Answer 1

Answer:

let the original price of the book = a

therefore,

rate of increase = 12%

increase in price = 12% of a

= 12/100 × a

= 0.12a

so,

incresed price

= a + 0.12a

= 1.12a

but,

increased prised = 145.60

so,

1.12a = 145.60

a = 145.60/1.12

= 130

The original price of the book is 130 Rs.
