Question

The price of a book is 4 rupees more than the
price of a pen. The price of a pencil is 2 rupees less
than the price of the pen. The total price of 5 books,
2 pens and 3 pencils is 74 rupees. What is the price
of each?​

Answer 1

Answer:

Pen = 6

Book = 10

Pencil = 4

Let

Price of pen = x

Price of book = x + 4

Price of pencil = x - 2

5(x + 4) + 2(x) + 3 (x - 2) = 74

5x + 20 + 2x + 3x - 6 = 74

10x + 14 = 74

10x = 74 - 14

10x = 60

X = 6

Put all the values in above equations

Pen = 6

Book = 10

Pencil = 4
