Answer 2

Answer:

$60 \: and \: 48$

Pens=60 and Pencils=48

Step-by-step explanation:

⇒  Let the number of pens be x.

⇒  Then, number of pencils =108−x

⇒  Cost of pens =7x

⇒  Cost of pencils =3(108−x)

According to the question,

7x+3(108−x)=564

7x+324−3x=564

4x+324=564

4x=564−324

4x=240

∴   x=240/4=60

⇒  Number of pencils =108−60=48

∴  The number of pens bought are 60 and pencil bought are 48.
