Question

the price of a book and pen together is 63 rupees the price of a book and 5 pens is 75 rupees what is the price of each​

Answer 1

Answer:

book=60. one pen cost= 3

Step-by-step explanation:

book + one pen price =63

book + 5 pen price = 75

cost of 4 pen= 75-63= 12

one pen cost = 3

book cost = 63-3 = 60

and one pen cost = 3

Answer 2

The price of the book is= 60 rupees.

The price of the pen is =3 rupess.

Calculations:

According to question,

• 1 book + 1 pen = 63 rupees.
• 1 book + 5 pens = 75 rupees.

Let the price of book be x and the price of the pen be y rupees.

So, the 2 equations according to the question will be:

    x + y =63............(i)

    x + 5y= 75.........(ii)

Subtracting the 2 equations we have:

      x + y =63

     x + 5y= 75

         - 4y = -12

            y = 3

Substituting the value of y in equation 1, we get:

            x + 3 = 63

            x  = 63- 3

            x = 60

Thus, the cost of the book = x= 60 rupees.

          The cost of each pen = y= 3 rupees
