Question

The price of a book and pen = 63 price of a book and price of 5 pens = 75 price of 4 pen?

Answer 1

Step-by-step explanation:

consider book =x and pen=y

x+y=63. (1)

x+5y=75. (2)

after subtracting both equations we get,

-4y= -12

y=3

put this value in equation (1)

x+3=63

x=60

hence price of book =x=60

price of pen=y=3

price of 4 pens =4*3=12 rs.
