Answer 1

Given :

• Price of pen and book together is 16 Rs.
• Price of a book is 10 more than pen

To Find :

• Price of each of the following

Solution :

Let price of book be x rupees, and price of pen be y rupees. So,

⇒x + y = 16 .......(1)

⇒x = y + 10 ........(2)

_____________________

Substitute value of x in (1)

⇒(y + 10) + y = 16

⇒y + 10 + y = 16

⇒2y + 10 = 16

⇒2y = 16 -10

⇒2y = 6

⇒y = 6/2

⇒y = 3

$\therefore$ Price of pen is 3 Rupees

_______________________________

Put value of y in (1)

⇒x + y = 16

⇒3 + y = 16

⇒y = 16 - 3

⇒y = 13

$\therefore$ Price of book is 13 rupees
