Question

The price of a note book and a pen is Rs.32.If the price of a book is Rs.12 more than the pen.Find the price of the note book.

Answer 1

Answer:22

Step-by-step explanation:

Let the price of pen be x

∴the price of book is x+12

∴x+(x+12)=32

∴ 2x+12=32

   2x=32-12

  2x=20

    x=10

x is the price of pen.

∵x+12 is price of book.

∴x+12+10+12=22
