Answer 1

Answer:

As it is given that, if he had sold the book at Rs 12 then he would have gained 10 %. So, Therefore, the Cost Price(CP) of the book is Rs 40

Answer 2

Answer:

40

Step-by-step explanation:

cost of book=x

80x/100+12=110x/100

80x+1200/100=110x/100

8000x+120000=11000x

3000x=120000

x=120000/3000

x=40

so cost price is 40
